Company profile<br />
Batero Gold Corp (TSX-V: BAT) has “something<br />
significant” in Colombia. President and<br />
CEO Brandon Rook told <strong>Mining</strong> <strong>Journal</strong><br />
that the company’s Batero-Quinchia<br />
project encompasses multiple porphyry<br />
gold targets and already justifies “long-term planning”.<br />
As of early January, the company was evaluating last<br />
year’s drill data to finalise a focused follow-up<br />
programme for 2012.<br />
Batero expects to publish its first independent<br />
resource estimate (by Roscoe Postle Associates Inc) in<br />
early 2012 and will immediately begin a Preliminary<br />
Economic Assessment.<br />
Mr Rook notes that the company has accomplished a<br />
lot in a short time. In 2008, he identified Colombia as<br />
having “amazing geology” and being a safe political<br />
environment in which to invest. He then started looking<br />
for a project that “ticked all the boxes”, securing the<br />
rights to Batero-Quinchia in 2010.<br />
High potential<br />
Batero is focused solely on Colombia, and, in particular,<br />
on the country’s emerging Middle Cauca porphyry gold<br />
and copper belt.<br />
This belt already hosts two significant gold deposits:<br />
Gran Colombia’s Marmato project (containing 12.4Moz<br />
of gold 20km north of Batero-Quinchia) and AngloGold<br />
Ashanti’s La Colosa (16.27Moz of gold 100km to the<br />
southeast). The belt also hosts the significant porphyry<br />
gold deposits of Titiribi, La Mina and Quebradona.<br />
At the centre of the latest excitement is Batero’s<br />
100%-owned 1,407ha property within the municipality<br />
of Quinchia in the department of Risaralda (some 55km<br />
north of Pereira, the regional capital). The region is<br />
considered socially stable and mining-friendly, and<br />
projects in the area are supported by comprehensive<br />
infrastructure, including roads, water and power.<br />
Three gold-copper porphyries were identified by an<br />
earlier programme in 2006 after early-stage drilling on<br />
the property. These porphyries are spaced over a 2km<br />
north-south strike length at elevations between 1,600m<br />
and 1,950m.<br />
The intrusives are composed of dykes and stocks<br />
emplaced in intermediate to felsic volcanic rocks of the<br />
Miocene Combia Formation and in Cretaceous basalts.<br />
All of the targets host gold and copper mineralisation.<br />
The mineralised zones encountered to date form<br />
part of a regional system covering more than 300ha.<br />
This district’s recognised core extends over 2km from<br />
La Cumbre through El Centro (encompassing the target<br />
areas of Manzanillo, La Lenguita and El Cedral) to Dos<br />
Quebradas.<br />
Achievements in 2011<br />
The company recently completed a 55,755m<br />
diamond-drill programme on time and on budget.<br />
Over the past year, Batero has aggressively delineated<br />
an area of gold and copper mineralisation at or near<br />
surface, expanding the overall footprint of the<br />
La Cumbre porphyry over 600m in a NW-SE direction<br />
and over 400m in a NE-SW direction. The company<br />
also extended mineralisation to a depth of 756m at<br />
the La Cumbre porphyry, which remains open at depth<br />
and in several directions.<br />
The company also drilled the northern area of the<br />
property at Dos Quebradas and extended the<br />
gold-copper system about 950m to the south through<br />
the El Centro zone about 950m.<br />
Mr Rook said he was “encouraged by the continuity<br />
of the Dos Quebradas gold-copper system from the<br />
El Centro porphyry mineralisation in the south through<br />
to the north concession boundary. The drill results show<br />
a large extension of structurally controlled related<br />
porphyry mineralisation within the basalt host rocks<br />
continuing to the northern limits of the concession.<br />
Also, the new results indicate that mineralisation is<br />
present near surface and at depth.”<br />
Exploration drilling at the El Centro zone led<br />
to a discovery of the La Lenguita porphyry along<br />
with near-surface high-grade gold epithermal<br />
mineralisation. Structurally-controlled epithermal<br />
gold mineralisation was also discovered along the<br />
Amarilla Structural Corridor east of the La Cumbre<br />
porphyry, which also overprints the porphyry systems<br />
at La Cumbre and El Centro.<br />
The company has identified continuous mineralisation<br />
along an approximate 2km strike length from the<br />
Dos Quebradas porphyry through the El Centro zone to<br />
the La Cumbre porphyry. Batero also made a discovery
