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 />

Employment group (MIGATE) announced<br />
Nathan Fisher, a third year apprentice<br />
based at George Fisher <strong>Mine</strong>, as their<br />
Mount Isa Apprentice of the Year<br />
As the Apprentice of the Year, Nathan<br />
was then selected <strong>to</strong> be a finalist <strong>to</strong><br />
represent Queensland at the Today’s<br />
Skills Tomorrow’s Leaders Forum, <strong>to</strong> be<br />
held in Canberra next month. The forum<br />
is designed for apprentices who excel in<br />
their traineeship and apprenticeship skills<br />
and will be the next generation of<br />
industry leaders.<br />
“The selection process involved a<br />
telephone interview with an independent<br />
judging panel. Then a few days later I<br />
found out I was chosen <strong>to</strong> be the<br />
Queensland representative at the<br />
Today’s Skills Tomorrow’s Leaders<br />
Forum,” said Nathan.<br />
Xstrata Zinc Maintenance and Support<br />
Manager, Tony Ross, was involved in the<br />
nomination process. “I would like <strong>to</strong> pass<br />
on my congratulations <strong>to</strong> Nathan on<br />
winning the MIGATE Apprentice of the<br />

Nathan has thanked his colleagues at<br />
George Fisher <strong>Mine</strong>. “I couldn’t have<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 />
participants <strong>to</strong> create an informed vision<br />
for their future and a realistic action plan<br />
<strong>to</strong> achieve their goals.<br />
“Nathan is a great asset <strong>to</strong> George Fisher<br />
<strong>Mine</strong> and will make a good ambassador<br />
for both Xstrata Zinc and MIGATE,”<br />
said Tony.<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 />

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 />

Biggest Morning Tea<br />
Various departments at Mount Isa <strong>Mine</strong>s<br />
held a morning tea in support of the Cancer<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 />
Thank you <strong>to</strong> James Roccheccioli<br />
for your contribution<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.

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.
