Leichhardt River Remediation<br />

Project complete<br />

Xstrata Mount Isa <strong>Mine</strong>s safely completed Stage 2 of the<br />

Leichhardt River Remediation Project on Friday 13 June,<br />

removing 120,000 <strong>to</strong>nnes of his<strong>to</strong>rical mine sediment material<br />

from the Leichhardt River and disposing it on the Mount Isa<br />

<strong>Mine</strong>s lease.<br />

Ed Turley, Environment Manager Xstrata Copper North<br />

Queensland, said that the final work was completed on Friday<br />

last week without incident and ahead of schedule.<br />

“Full credit is extended <strong>to</strong> all those involved in this project,<br />

including Xstrata employees, earth moving and plumbing<br />

contrac<strong>to</strong>rs, security staff, and Mount Isa City Council<br />

employees, who all helped <strong>to</strong> ensure that the Stage 2 works<br />

were completed safely and on time,” said Ed.<br />

The purpose of the Leichhardt River project was <strong>to</strong> identify and<br />

remove his<strong>to</strong>rical mine sediments from the riverbed which have<br />

been exposed over time as a result of natural erosion within the<br />

river system. The Stage 2 works involved 252 hours of operation<br />

over 24 days.<br />

“During the next six weeks, we will undertake grid sampling of<br />

the entire Stage 2 area of work within the Leichhardt River, and<br />

repeat this process following the <strong>2008</strong>/09 wet season <strong>to</strong> help<br />

ensure and verify that all exposed his<strong>to</strong>rical mine sediment has<br />

been removed,” said Ed.<br />

“Follow-up sampling will then be conducted post-wet season<br />

on an annual basis through <strong>to</strong> 2011 <strong>to</strong> ensure that river flows<br />

and natural erosion do not uncover any additional mine<br />

sediments,” he said<br />

“In addition <strong>to</strong> completing the project, we are in the process of<br />

revegetating and beautifying a vacant block of land at the end<br />

of Sunflower Street that was used by the trucks <strong>to</strong> access the<br />

river bed,” said Ed<br />

The Facts<br />

The project was completed safely and on time<br />

70,000 cubic metres (120,000 <strong>to</strong>nnes) of his<strong>to</strong>rical mine<br />

sediment was removed<br />

3,894 trips were made from the Leichhardt River bed <strong>to</strong><br />

Gardenia Gate <strong>to</strong> dispose of the material safely on the<br />

Mount Isa <strong>Mine</strong>s lease<br />

10.3 million litres of water from the mine was used for<br />

dust suppression<br />

His<strong>to</strong>rical mine sediment was replaced with<br />

approximately 15,000 cubic metres (25,000 <strong>to</strong>nnes)<br />

of clean fill from our quarry<br />

There were no exceedances on the dust or noise<br />

moni<strong>to</strong>rs registered during the project<br />

All operational areas within the Leichhardt River bed<br />

were graded on completion of the project

An Introduction <strong>to</strong> the Copper Refinery’s Labora<strong>to</strong>ry<br />

The labora<strong>to</strong>ry is an integral part of<br />

the Townsville Copper Refinery’s<br />

(CRL) operation. The first labora<strong>to</strong>ry<br />

building (southern) was constructed<br />

at the time the refinery was built and<br />

began operation in 1959. The second<br />

(northern) wing of the labora<strong>to</strong>ry<br />

followed in the mid 1960s with<br />

the decision <strong>to</strong> purchase the first<br />

mass spectrometer. At the peak of<br />

operations, 15 chemists, assayers, and<br />

labora<strong>to</strong>ry technicians were employed<br />

in the labora<strong>to</strong>ry.<br />

Today, the ISO 9001 accredited<br />

labora<strong>to</strong>ry is staffed by a team of three<br />

labora<strong>to</strong>ry analysts – Marcia Bacon,<br />

Geoff Douthett and Scott Foster – who<br />

perform all refinery sample analysis and<br />

required services including:<br />

analysis of process solutions<br />

and effluents <strong>to</strong> moni<strong>to</strong>r plant<br />

operations and ensure statu<strong>to</strong>ry<br />

compliance;<br />

preparation and analysis of anode<br />

samples (CRL and Mount Isa <strong>Mine</strong>s)<br />

<strong>to</strong> ensure compliance with elemental<br />

composition requirements;<br />

preparation and analysis of samples<br />

from all cathode produced <strong>to</strong> ensure<br />

quality compliance and <strong>to</strong> enable<br />

assay report generation;<br />

Analyst, Scott Foster, loading a sample in<br />

the Glow Discharge Mass Spectrometer.<br />

preparation and analysis of anode<br />

slimes samples <strong>to</strong> enable shipment<br />

assay report generation; and<br />

provision of technical support <strong>to</strong><br />

plant operations and project work.<br />

The team routinely processes 1,000<br />

samples per month, performing over<br />

8,000 analyses on these samples. This<br />

high throughput is achieved by using<br />

highly au<strong>to</strong>mated instruments that<br />

have replaced classical wet chemical<br />

techniques. Instruments used include:<br />

Inductively Coupled Plasma Emission<br />

Spectrometer (ICP) – used <strong>to</strong> analyse<br />

process solutions and solutions<br />

prepared from process solids;<br />

Optical Emission Spectrometer (OES)<br />

– used <strong>to</strong> all analyse cathode and<br />

anode samples;<br />

Glow Discharge Mass Spectrometer<br />

(GDMS) – used <strong>to</strong> analyse trace<br />

components in cathode samples.<br />

Last year, the labora<strong>to</strong>ry re-commenced<br />

providing contract cathode copper<br />

analytical services <strong>to</strong> domestic and<br />

overseas cus<strong>to</strong>mers. Currently there<br />

are four domestic and two overseas<br />

cus<strong>to</strong>mers – Oman and Myanmar –<br />

who are sending an average of<br />

80 cathode samples per month<br />

for analysis.<br />

The income generated from this service<br />

is ensuring labora<strong>to</strong>ry operations are<br />

more cost effective with improved<br />

utilisation of specialist equipment.<br />

Thank you Keith Lowrey for your<br />

done it without Andy Watson and<br />

Cyril Murphy’s help <strong>to</strong> give me the extra<br />

exposure <strong>to</strong> other mining equipment<br />

<strong>to</strong> help me gain more experience,”<br />

said Nathan.<br />

Today’s Skills Tomorrow’s Leaders Forum<br />

will be launched by the Governor-<br />

General at Government House in<br />

Canberra. Led by Lifestyle Strategist,<br />

Ian Hutchinson, the forum will guide<br />

Diamond drilling teams achieve record month<br />

May was a record month for diamond drillers at George Fisher<br />

<strong>Mine</strong> (GFM) with a <strong>to</strong>tal of 13,877 metres drilled during the month.<br />

Leigh Neindorf, Zinc Lead Operations <strong>Mine</strong> Projects Manager,<br />

said the figure comprises 12,044 metres of diamond drilling and<br />

1,833 metres of reverse circulation drilling.<br />

“This is a remarkable effort on behalf of all diamond drillers<br />

from the Mount Isa <strong>Mine</strong>s operation. The figure consists of<br />

4,998 metres from the three surface drilling rigs operated<br />

by Major Drilling, and 8,879 metres from the seven underground<br />

diamond drill rigs operated by Xstrata and Barminco,” said Leigh.<br />

Drilling is done <strong>to</strong> provide samples which will in turn be logged<br />

and assayed (the process whereby rock samples are analysed for<br />

the concentration of metal) <strong>to</strong> improve the geological knowledge<br />

of an area.<br />

Xstrata Copper’s Diamond Drilling Team also made a great<br />

contribution <strong>to</strong> the business during May, drilling 5,613 metres<br />

of diamond drill core with the three rigs employed at George<br />

Fisher <strong>Mine</strong>.<br />

Nick Slade, Manager MICO Coordination, said “with the<br />

remaining three drilling rigs in the Mount Isa Copper Operations,<br />

a <strong>to</strong>tal of 9,485 metres of diamond drilling was completed during<br />

the month of May across the operations by our own workforce.<br />

Core samples produced by the<br />

Diamond Drilling team.<br />

“The month of May was also an injury free month for the<br />

Diamond Drilling Department in Xstrata Copper. These safety and<br />

production achievements combined <strong>to</strong> form Xstrata Copper’s<br />

best month in 10 years for our in-house diamond drilling and<br />

raiseboring team. They should take pride in their achievement<br />

and celebrate what they are capable of achieving as we go<br />

forward,” added Nick.<br />

The Xstrata management team would like <strong>to</strong> thank and<br />

congratulate all involved in diamond drilling across the Mount<br />

Isa <strong>Mine</strong>s lease<br />

Every year, St Kieran’s Year 5 students from Mount Isa visit Cloncurry for a three day school camp. The camp<br />

involves students travelling out <strong>to</strong> EHM <strong>to</strong> experience a world class working operation. This year, students<br />

commented on how “big” everything was at the open pit mine and how much fun the <strong>to</strong>ur was.

A day in the life of: a coke burner<br />

Have you ever wondered what is involved in the coke making<br />

process at Xstrata Zinc’s Bowen Coke Works (BCW)?<br />

Established in 1933, BCW uses a special type of coal called<br />

coking coal <strong>to</strong> make coke. This is sourced from Collinsville coal<br />

mine. The coking process converts this coal in<strong>to</strong> coke, most of<br />

which is used as a fuel in the Mount Isa <strong>Mine</strong>s’ lead smelter<br />

blast furnace. The remaining product is sold domestically<br />

and overseas.<br />

Cokemaking requires specialist expertise. Just ask John Williams,<br />

employee of 34 years with approximately 10 years as a burner<br />

at BCW, why this process is so challenging and he’ll tell you,<br />

“because it all comes down <strong>to</strong> using your judgement. There are<br />

no mechanical processes – you need <strong>to</strong> be able <strong>to</strong> make<br />

judgements using your own eyes.”<br />

By the time the crushed coal gets <strong>to</strong> John and the team for<br />

weighing, levelling, pushing and charging, it has already gone<br />

through a series of grinding <strong>to</strong> get it down <strong>to</strong> a fine size.<br />

There are three grades of coke: Metallurgical Coke (100 <strong>to</strong><br />

45 millimetres), Nut Coke (45 <strong>to</strong> 10 millimetres), and Coke<br />

Breeze which is less than 10 millimetres. Depending upon the<br />

coal type, coals are blended in different ratios <strong>to</strong> provide a suitable<br />

mix for the coking process. Coals are crushed down <strong>to</strong> a size of<br />

under three millimetres (more than 90%) in a hammer mill then<br />

conveyed <strong>to</strong> a s<strong>to</strong>rage bin above the oven battery.<br />

A predetermined charge of coal is loaded from the s<strong>to</strong>rage bin<br />

in<strong>to</strong> two canister cars. All charges are weighed accurately using<br />

a weight bridge. Canister cars run along rails on <strong>to</strong>p of the oven<br />

battery <strong>to</strong> the fine coal bins ready <strong>to</strong> be put in<strong>to</strong> the ovens –<br />

a process known as charging.<br />

The charge is loaded in<strong>to</strong> the oven from the bot<strong>to</strong>m of the<br />

canister car through a series of port (charge) holes. To ensure<br />

the charge is evenly distributed, a machine called a ram,<br />

which travels alongside the oven battery, is used <strong>to</strong> level out<br />

the coal bed.<br />

The coal inside the oven ignites due <strong>to</strong> the heat and drives off<br />

the volatiles. Air <strong>to</strong> the oven is carefully controlled <strong>to</strong> combust<br />

these volatiles and heat the oven charge.<br />

Coke remains in the ovens for three days where it is heated<br />

through regular adjustments <strong>to</strong> the oven damper tiles <strong>to</strong><br />

ensure the heat inside the oven is at the correct temperature.<br />

Using their judgment and experience, the coke burners control<br />

and restrict the amount of air entering the oven using a damper<br />

tile which is placed across the <strong>to</strong>p of the oven.<br />

“Everything is determined by the eye. I use my knowledge and<br />

experience <strong>to</strong> look inside the oven and make any adjustments,”<br />

said John.<br />

“However, the key <strong>to</strong> good judgement is through experience,”<br />

he said. “As for our team, we’ve got it down pat. Most of<br />

the blokes have been here for at least four <strong>to</strong> five years.<br />

Good judgement comes only from experience.”<br />

A coke burner’s week is based around three cycles. Once the<br />

oven is charged, the coal ignites due <strong>to</strong> the heat in the oven.<br />

The coal is left in the oven for three days (during the week) or<br />

four days (over the weekend), by which time the volatile matter<br />

in the coal is released and burnt off. The two, three day week<br />

cycles; Monday <strong>to</strong> Wednesday, and Wednesday <strong>to</strong> Friday,<br />

burns 7.2 <strong>to</strong>nnes of coke per oven, while the four-day burn<br />

cycle from Friday <strong>to</strong> Monday burns 9.36 <strong>to</strong>nnes of coke per oven.<br />

The recovery rate for this <strong>to</strong>nnage is approximately 72%.<br />

Because of the cyclical nature of the job, John and the other<br />

five coke burners at BCW take it in turns <strong>to</strong> cover the Monday<br />

<strong>to</strong> Sunday shift.<br />

“My day starts at 6am when I begin by making adjustments<br />

<strong>to</strong> the ovens before attending the PASS meeting. There are<br />

54 ovens at the coke works and each oven takes<br />

10 <strong>to</strong> 12 minutes <strong>to</strong> charge, level and push,” said John.<br />

“At around 12pm and then again at around 4.30pm, I do a full<br />

check of every oven <strong>to</strong> ensure the oven is burning correctly and<br />

make any adjustments. We let the coal burn for three <strong>to</strong> four<br />

hours at a time but continual moni<strong>to</strong>ring is the key <strong>to</strong> ensuring<br />

the successful burning of the coal. On a production day, the<br />

last oven is pushed at around 5.30pm. After pushing has been<br />

completed, I make any further adjustments <strong>to</strong> the other ovens<br />

before finishing for the day,” he said.<br />

John has seen a lot of changes <strong>to</strong> the coke making process over<br />

the past 30 years. “When I started in 1974, we only used <strong>to</strong><br />

charge 27 ovens per day and now we charge 54. The team has<br />

also grown in size. Coke burning used <strong>to</strong> be a one-man job and<br />

now there are six of us <strong>to</strong> cover the weekly shifts but at the<br />

same time we are doing an increased range of duties when not<br />

on the coke burning roster.”<br />

“One of the most enjoyable aspects of working here is the<br />

mateship,” said John. “We’re a close group of blokes and<br />

always help each other out. The flexibility provided by the team<br />

mates makes for a good work-life balance. We’re always there<br />

<strong>to</strong> back each other up.”<br />

After three or four days in the oven, the coke is ready <strong>to</strong> be<br />

pushed out of the oven. The red hot coke is pushed in<strong>to</strong> a hot<br />

car using a ram and travels along the track <strong>to</strong> the quench <strong>to</strong>wer<br />

where it is cooled using re-cycled water.<br />

The cooled coke is then pushed from the hot car and conveyed<br />

<strong>to</strong> a crushing and screen plant where the coke is sized in<strong>to</strong><br />

different fractions <strong>to</strong> suit cus<strong>to</strong>mer requirements. It is then<br />

loaded for despatch and the cokemaking production cycle<br />

begins again

Safety reminder<br />

All employees are reminded that operation of vehicles both<br />

on and off the mine lease is governed by the legislative<br />

requirements of the Queensland Transport Operations<br />

(Road Use Management) Act 1995. Operating a mo<strong>to</strong>r vehicle<br />

while using a mobile phone (that is not on a hands-free device)<br />

is not only unsafe, but is illegal and prohibited both on and<br />

off site. Not complying with this rule on site may result in<br />

disciplinary action as a result of contravening a safety rule.<br />

Breaking this rule off site is a bookable traffic offence

Xstrata hosts Kalkadoon site <strong>to</strong>ur<br />

Xstrata Mount Isa <strong>Mine</strong>s’ Environment and Community<br />

Relations teams hosted a site <strong>to</strong>ur of the tailings dams<br />

and the Leichhardt River Remediation Project works for<br />

several direc<strong>to</strong>rs of the Kalkadoon Community Pty Ltd<br />

and native title applicants in early June.<br />

The site <strong>to</strong>ur was used as an orientation opportunity for<br />

the Kalkadoon representatives <strong>to</strong> become familiar with<br />

the tailings dam area before cultural heritage surveys are<br />

held in coming months.<br />

Following a site induction conducted by Senior<br />

Environmental Advisor, Anne Williams, Indigenous Affairs<br />

Advisor, Zane Hughes, and Anne escorted the group <strong>to</strong><br />

the tailings dams <strong>to</strong> discuss the production and the<br />

environmental management aspects of the tailings dams.<br />

Issues such as water management, water reuse, seepage<br />

collection and moni<strong>to</strong>ring, dust control and closure<br />

planning opportunities were also discussed. Future plans<br />

for the design of the tailings dams and the benefits of<br />

changed management in enabling increased capture of<br />

water for reuse were explained, with a focus on areas<br />

where cultural heritage clearances will be required for<br />

future projects.<br />

The group also visited the Leichhardt River <strong>to</strong> inspect<br />

the Stage 2 works of the Leichhardt River Remediation<br />

Project.<br />

During the next quarter, Xstrata will also host a two day<br />

forum for the Kalkadoon Community Pty Ltd Board of<br />

direc<strong>to</strong>rs <strong>to</strong> discuss a number of environmental,<br />

community, exploration and contracting projects<br />

Skills for the future<br />

The Xstrata Skills Centre is hosting<br />

an eight week Skills for the Future<br />

program for Year 9 and 10 school<br />

students, giving them a taste of life<br />

as an apprentice.<br />

Renita Casey from Spinifex College<br />

has been attending the Skills for the<br />

Future program and is learning about<br />

safety systems, electronics, hand <strong>to</strong>ols<br />

and soldering.<br />

“Our exercise is <strong>to</strong> build a robot<br />

from screws and steel, and solder it<br />

<strong>to</strong>gether, which is a lot of fun,” said<br />

Renita, who is considering becoming a<br />

school-based apprentice.<br />

Renita’s instruc<strong>to</strong>r at the Skills Centre,<br />

Kerry Brisbane, Electrical Apprentice<br />

Team Leader, said the students take<br />

the Skills for the Future program<br />

very seriously.<br />

Dave Watson, Skills Centre Superintendent, with student Renita Casey.<br />

“It is similar <strong>to</strong> being an apprentice<br />

because the students undergo an<br />

induction, pre-employment medical<br />

and use their Personal Protective<br />

Equipment (PPE) and workwear.<br />

They are a very dedicated and keen<br />

group of students,” said Kerry<br />

“In previous years, Year 9 students<br />

have been involved, however this is the<br />

first year that Year 10 has also come<br />

onboard and it’s proving <strong>to</strong> be very<br />

successful,” said Kerry

Building community and<br />

cultural resilience<br />

The Queensland Arts Council (QAC), an XCPP NQ partner,<br />

will hold a series of workshops about resilience in<br />

communities later this month in Mount Isa.<br />

The forum will aim <strong>to</strong> ensure we better understand how<br />

our communities tick and their influence on the landscape<br />

and lifestyles of our regions.<br />

The QAC North West Regional forum, titled Bouncing<br />

Back – Playing <strong>to</strong> your Strengths, will be held in Mount Isa<br />

on 26 and 27 <strong>July</strong> at the Xstrata Entertainment Centre at<br />

Buchanan Park.<br />

Ms Ros Derrett OAM, Head of the Office of Regional<br />

Engagement at Southern Cross University, will facilitiate<br />

the forums. Ros has worked extensively in education,<br />

<strong>to</strong>urism, community cultural development and arts<br />

administration in Australia and overseas, and was the<br />

facilita<strong>to</strong>r for the inaugural QAC Forum Series in 2004<br />

funded by the XCPP NQ.<br />

“Once we understand who we are as a community and<br />

determine where we want <strong>to</strong> be, we can bring <strong>to</strong>gether<br />

the appropriate resources we need <strong>to</strong> enhance the quality<br />

of life for residents and visi<strong>to</strong>rs. This will ensure creativity,<br />

prosperity and liveability for all stakeholders and<br />

demonstrate our resilience when the challenges arise,”<br />

said Ms Derrett.<br />

The forum workshops will provide a special lens on<br />

community resilience and will help bring individuals and<br />

groups <strong>to</strong>gether. These partnerships are important and<br />

require a special approach so that each stakeholder group<br />

in the community gets the best from the relationship<br />

Council’s Biggest Morning Tea.<br />

There were cakes galore at Central Office<br />

as employees and senior management<br />

joined <strong>to</strong> raise vital funds for the worthy<br />

cause. A <strong>to</strong>tal of $231 was raised.<br />

Over at the Xstrata Copper Exploration<br />

offices, Lina Will, Compliance and Travel<br />

Coordina<strong>to</strong>r, organised a morning tea,<br />

as she does every year <strong>to</strong> coincide with her<br />

birthday. This year Lina invited the entire<br />

Strategic Planning Department and raised a<br />

combined <strong>to</strong>tal of over $310.<br />

Also present at the Biggest Morning Tea<br />

was Bill Duchatel who was a guest of the<br />

Strategic <strong>Mine</strong> Planning team. Bill worked<br />

on the 500 Orebody in the mid <strong>to</strong> late 60s<br />

as part of the Sub Level Caving team and<br />

was onsite <strong>to</strong> provide the 500 Orebody<br />

pre-feasibility study team with some<br />

his<strong>to</strong>rical background as part of an all day<br />

review. Bill explained the challenges<br />

encountered by his team when mining in<br />

the reactive ore of the 500 Orebody.<br />

The review helped define the operational<br />

solutions that were developed <strong>to</strong> address<br />

the challenges of mining in reactive ground.<br />

Lead Smelter introduces porta count machine<br />

The lead smelter has introduced a new<br />

porta count machine <strong>to</strong> effectively carry<br />

out ‘respira<strong>to</strong>r-fit testing’ for its employees.<br />

As part of the new starter procedure,<br />

respira<strong>to</strong>r-fit tests are conducted so that<br />

the employee is fitted with the most<br />

suitable type of respira<strong>to</strong>r before they start<br />

work in the lead smelter. The respira<strong>to</strong>r-fit<br />

test is important as there are several<br />

different types and sizes of respira<strong>to</strong>rs in<br />

use. In addition, one type and size may be<br />

more effective than another, depending on<br />

the employee’s face shape.<br />

Respira<strong>to</strong>rs are used as prevention against<br />

lead absorption through inhalation, so it is<br />

very important that the respira<strong>to</strong>r used is<br />

the correct type and fit for the user.<br />

Respira<strong>to</strong>r pre-start checks are also carried<br />

out by employees at the beginning of each<br />

shift as part of the ongoing maintenance of<br />

this piece of Personal Protective Equipment.<br />

By using the porta count machine, the<br />

same faults can be identified as would be in<br />

the pre-start test, however the added<br />

feature of the machine is that it assigns a<br />

‘fit fac<strong>to</strong>r’ <strong>to</strong> the respira<strong>to</strong>r. This ‘fit fac<strong>to</strong>r’<br />

is determined through a series of tests<br />

while the employee is wearing the<br />

respira<strong>to</strong>r. These include side <strong>to</strong> side head<br />

movements, checking that breathing is<br />

normal, and determining their ability <strong>to</strong><br />

speak while wearing the respira<strong>to</strong>r.<br />

If results returned are lower than expected,<br />

the respira<strong>to</strong>r can be adjusted. For example,<br />

the elastic strap can be replaced while there<br />

is still some elasticity rather than wait until<br />

there is none. This <strong>to</strong>ol allows us <strong>to</strong> be<br />

more pro-active than reactive.<br />

My colleagues don’t know this, but...<br />

Importantly, the porta count machine does<br />

not replace the need for employees <strong>to</strong><br />

conduct pre-start checks. It is an added<br />

<strong>to</strong>ol that is used <strong>to</strong> ensure that the<br />

respira<strong>to</strong>rs are the appropriate size for the<br />

individual employee and are at optimum<br />

effectiveness.<br />

BSOC Environmental Pad Trial<br />

In order <strong>to</strong> yield world best practice rehabilitation outcomes,<br />

Black Star Open Cut mine (BSOC) has commissioned and<br />

sponsored significant research on waste rock dump cover system<br />

designs and the role of vegetation in cover systems.<br />

In 2006, specialist consultants from Canada were employed <strong>to</strong><br />

mathematically model potential moisture s<strong>to</strong>re and release cover<br />

system options. During May this year, a field trial commenced <strong>to</strong><br />

identify the most economically and environmentally beneficial<br />

moisture s<strong>to</strong>re and release cover system option for the BSOC<br />

waste rock dumps.<br />

Xstrata Zinc’s BSOC<br />

operation has sponsored<br />

an ACMER (Australian<br />

Centre for <strong>Mine</strong>rals<br />

Extension and Research)<br />

research program that<br />

will provide vital<br />

knowledge with respect<br />

<strong>to</strong> the role that<br />

vegetation plays in cover<br />

systems as they operate<br />

<strong>to</strong> minimise moisture<br />

percolation in<strong>to</strong> waste<br />

rock dumps. Currently<br />

very little is known about<br />

the role of vegetation in<br />

cover systems, so BSOC’s<br />

research will help ensure<br />

environmentally safe<br />

waste rock dumps and<br />

excellent rehabilitation<br />

outcomes, not only in<br />

Mount Isa but also at<br />

various other Xstrata<br />

operations world-wide.<br />

From left <strong>to</strong> right: Daniel Taylor, Dave Brennan, Jonythan Maps<strong>to</strong>ne,<br />

and Anu Datta pictured at the BSOC waste rock cover trial site.<br />

Over the period of one month, three scientifically instrumented<br />

test plots were constructed from approximately 13,000 cubic<br />

metres of non-acid forming waste rock. The test plots were<br />

constructed in lifts with one standing at four metres and the<br />

others being two metres tall. One of the two metre tall pads<br />

included a 0.5 metre compacted layer of non acid waste.<br />

The project also involved complex excavations for the installation<br />

of a range of scientific instrumentation which detects moisture<br />

content and soil suction. Within each of the test plots, up <strong>to</strong><br />

three sets of 16 moisture and 16 soil suction sensors were<br />

installed vertically from the surface of the cover at various depths<br />

of up <strong>to</strong> seven metres <strong>to</strong> measure the movement of moisture in<strong>to</strong><br />

the cover which would come from the infiltration of rain and then<br />

movement of moisture out of the cover because of evaporation<br />

and plants drawing on s<strong>to</strong>red moisture. It is known that in hot<br />

areas like Mount Isa, evaporation can draw moisture from<br />

more than two metres under the ground surface. An important<br />

part of the construction of the test plots included burying<br />

three four-metre-diameter rainwater tanks. These will enable us<br />

<strong>to</strong> measure water ingress rates through the various cover system<br />

configurations and compare this <strong>to</strong> the sensor readings.<br />

The data collected from instrumentation in these test plots will<br />

enable us <strong>to</strong> verify that the mathematical model developed for<br />

the cover designs<br />

effectively mimics what<br />

happens in reality and<br />

proves that the cover<br />

system will be effective<br />

in the long term. It will<br />

also allow the design <strong>to</strong><br />

be refined over time.<br />

Xstrata Zinc’s General<br />

Manager <strong>Mining</strong><br />

Anthony Kocken, said<br />

“This project involved<br />

numerous individuals<br />

undertaking a wide<br />

variety of duties and one<br />

of the greatest<br />

accomplishments of this<br />

initiative is the extent <strong>to</strong><br />

which BSOC’s personnel<br />

pulled <strong>to</strong>gether <strong>to</strong> not<br />

only get the job done,<br />

but get it done well.<br />

“All construction and<br />

excavation for this<br />

complex initiative was<br />

undertaken by BSOC’s Civil Crew. It is a real accomplishment that<br />

the project was completed safely without incident and within the<br />

expected timeframes,” said Anthony.<br />

“The individuals on the Civil Crew should be proud of themselves<br />

and their excellent achievements on this project. These individuals<br />

have significantly contributed <strong>to</strong> an important project which will<br />

yield significant environmental outcomes and could save us<br />

millions of dollars by reducing the thickness of the non acid cover<br />

on our waste rock dump,” he added.<br />

The initiative <strong>to</strong>ok a month <strong>to</strong> complete and involved over<br />

1,000 man and equipment hours. The next phase of the initiative<br />

involves building an extra two plots which specifically examine<br />

the role of vegetation in cover systems. This phase is expected <strong>to</strong><br />

commence in the coming months

The Open Pit Opera<strong>to</strong>r’s Experience<br />

Following on from last month’s Myuma<br />

s<strong>to</strong>ry we bring you: The Open Pit<br />

Opera<strong>to</strong>r’s Experience.<br />

The Open Pit Opera<strong>to</strong>r’s Experience is<br />

prepared by Black Star Open Cut (BSOC)<br />

mine employees and is a series of<br />

vocational talks given <strong>to</strong> Indigenous<br />

participants seeking exposure <strong>to</strong> the<br />

mining industry. One of the presenters<br />

is Drill and Blast Leading Hand and local<br />

Indigenous woman, Wanita Gosbee.<br />

Wanita had her first taste of mining<br />

when she attended a mining access<br />

program at the Hard Times <strong>Mine</strong>.<br />

From there Wanita worked for a number<br />

of contrac<strong>to</strong>rs on the lease before<br />

starting with BSOC. It has been an<br />

onwards and upwards career progression<br />

for Wanita who has recently been acting<br />

in the position of BSOC’s Drill and<br />

Blast Supervisor.<br />

“In the role of Drill and Blast Leading<br />

Hand, I look after a crew of seven people<br />

<strong>to</strong> ensure our daily tasks are undertaken.<br />

I’m the blast controller, which means I’m<br />

responsible for charging and stemming<br />

holes, then connecting all the holes<br />

<strong>to</strong>gether. The health and safety of the<br />

employees is my highest priority.<br />

Therefore it is critical that I ensure the<br />

area is clear prior <strong>to</strong> firing,” said Wanita.<br />

An explanation of Wanita’s job<br />

description and role expectations<br />

accompanied by video footage of BSOC<br />

is a major part of The Open Pit<br />

Opera<strong>to</strong>r’s Experience presentation<br />

which she delivered <strong>to</strong> students from the<br />

Spinifex Junior campus, as well as the<br />

Myuma visi<strong>to</strong>rs <strong>to</strong> BSOC.<br />

“I’m more than happy <strong>to</strong> provide advice<br />

<strong>to</strong> others wishing <strong>to</strong> enter the mining<br />

industry. I have a diverse range of work<br />

experience, from living and working on<br />

my family’s cattle property <strong>to</strong> now<br />

holding a shot firer’s licence. I enjoy<br />

sharing my experiences with people <strong>to</strong><br />

help them <strong>to</strong> achieve their goals or<br />

obtain future job opportunities within<br />

the mining industry,” Wanita said.<br />

“But there’s one piece of advice that has<br />

always helped me, and that’s <strong>to</strong> turn up<br />

<strong>to</strong> work with the right attitude,” she said.<br />

As a result of Wanita’s presentation <strong>to</strong><br />

Myuma visi<strong>to</strong>rs at Black Star Open Cut<br />

mine, a number of students graduated<br />

from a structured vocational training<br />

program with Xstrata Zinc. Two students<br />

were located at BSOC, one in administration<br />

at George Fisher <strong>Mine</strong> (GFM) and one at<br />

the workshop at GFM<br />

Wanita Gosbee, Lyle James, and Anthony Kocken at Black Star Open Cut mine.

Australian coat of arms and, some say, were chosen because they move forward<br />

and find it difficult <strong>to</strong> go backwards. Their positions have been switched, left and<br />

right, <strong>to</strong> represent the switch in the Governments attitude.<br />

They are surrounded by the stars of the Southern Cross which, like Aboriginal people,<br />

have been here since the beginning of time. There must be a change in attitudes<br />

problems that they can. Governments must not look at Indigenous problems and<br />

say “This is going <strong>to</strong> cost <strong>to</strong>o much <strong>to</strong> fix” or “The problem is <strong>to</strong>o big”.<br />

Now is the best time because we are in a time of great prosperity which is ripped<br />

from the land that rightly belongs <strong>to</strong> Aboriginal people.<br />

For the background we have used the colours of the land, the sorry is in blue<br />

representing water and a healing point. The Southern Cross is in the colours of the<br />

sunset, the time when it first comes out. The lines connecting the Southern Cross<br />

represent the spirits of our ances<strong>to</strong>rs that are looking down on us and keeping an eye<br />

on us. The lines are black for our ances<strong>to</strong>rs and the orange is power and knowledge<br />

that they have and have given.<br />

Aboriginals and Torres Strait Islanders’ future, like this poster, can be built on the<br />

Handlebar Hill Open Cut – a preferred training ground<br />

Third Year University of Ballarat geology<br />

students visit Handlebar Hill Open Cut mine.<br />

Xstrata Zinc’s Handlebar Hill Open Cut (HHOC) mine last month<br />

cemented its place as a preferred training ground as a group of<br />

geology students from the University of Ballart visited the mine<br />

<strong>to</strong> complete mapping exercises as part of their geology<br />

curriculum.<br />

The third year undergraduate students participated in a training<br />

program organised between the university and Xstrata Zinc<br />

which involved mapping of the Mount Isa Valley mineral<br />

outcrops and areas of the HHOC lease.<br />

“Mount Isa provides a varied and complex geology which is<br />

perfect for our third year students <strong>to</strong> map and study,” said<br />

Stafford McKnight, Lecturer in <strong>Mine</strong>ralogy and Petrology for the<br />

School of Science and Engineering at the University of Ballarat.<br />

“The aim of this exercise was geographical mapping and taking<br />

advantage of the particularly good geology in and around<br />

Mount Isa and Cloncurry,” said Stafford.<br />

“The students mapped in pairs; completed a detailed study of<br />

rock structures, and then produced two maps and two reports<br />

<strong>to</strong> accompany a 15 minute presentation <strong>to</strong> senior Xstrata<br />

employees,” he said.<br />

He said new training initiatives like this will help <strong>to</strong> combat a<br />

huge shortage of trained professionals within the industry<br />

Diabetes and the Glycaemic Index<br />

MEDICAL<br />

Approximately one in four Australians<br />

suffer from either Diabetes or impaired<br />

glucose <strong>to</strong>lerance. These statistics are on<br />

the incline. According <strong>to</strong> the Australian<br />

Institute of Health and Welfare (<strong>2008</strong>),<br />

a large number of diabetes cases still<br />

remain undiagnosed, as there are often<br />

no symp<strong>to</strong>ms.<br />

Fortunately, the increased awareness<br />

of the Glycaemic Index (GI) can have<br />

beneficial outcomes for both Diabetic and<br />

non-diabetic people. The GI refers <strong>to</strong> how<br />

rapidly carbohydrate-containing foods<br />

are broken down in the digestive system<br />

and absorbed in<strong>to</strong> the blood stream.<br />

Carbohydrates that enter the blood<br />

stream quickly have high GI values, and<br />

lower GI carbohydrates are more gradually<br />

absorbed in<strong>to</strong> the blood stream.<br />

High carbohydrate foods include breads,<br />

cereals, pasta, some starchy vegetables,<br />

fruits, legumes and milk. It is the<br />

characteristics of carbohydrates and<br />

other elements (fats, acidity) in foods that<br />

influence GI. For example carbohydrates<br />

that are heavily processed and low in fibre<br />

such as white bread or finely milled flour,<br />

cause a quick rise in blood sugar levels<br />

(BSLs). On the other hand, carbohydrates<br />

that contain high levels of soluble fibre<br />

and preserve the shell of the cells, such<br />

as multigrain bread and soy products, are<br />

more difficult <strong>to</strong> digest and are therefore<br />

broken down slowly.<br />

What foods are high,<br />

intermediate or low GI?<br />

High (GI 70 or more) – white rice, high<br />

sugar cereals, white pota<strong>to</strong><br />

Intermediate (GI 56-69) – bran muffin,<br />

rockmelon and most dried fruits<br />

Low (GI 55 or less) – pears, sourdough<br />

bread and sweet pota<strong>to</strong><br />

How does GI help with diabetes?<br />

People with diabetes have difficulty<br />

regulating their BSLs and research<br />

indicates that incorporating low GI<br />

foods in<strong>to</strong> all meals can have many<br />

benefits including:<br />

Lowering the average BSL and reducing<br />

marked spikes and troughs,<br />

Improve the body’s ability <strong>to</strong> use<br />

glucose for energy,<br />

Lower ‘bad’ blood fats and improve<br />

good cholesterol, and<br />

Assists in weight management as it<br />

improves satiety after a meal.<br />

A balanced diet that is high in<br />

fruit, vegetables and wholegrain<br />

carbohydrates, and is low in<br />

saturated fat, salt, alcohol and<br />

refined sugars, will assist all people<br />

<strong>to</strong> live a healthier lifestyle.<br />

Taking risks can take lives.<br />

Be rail smart.<br />

With both rail and road traffic continually increasing the need <strong>to</strong> stay<br />

alert and be aware of potential dangers at level crossings is essential.<br />

Always be on alert for a second train and always pay attention <strong>to</strong><br />

signs and signals.<br />

If you take a risk at a level crossing you are not only risking your<br />

own life, you are risking the lives of others. Be smart, be RailSmart.
