NUEVA ESPERANZA PROJECT
Field operations at the Nueva Esperanza project has
focused on the completion of resource and geotechnical
drilling at Teterita and completion of sterilisation
drilling over proposed sites for mine infrastructure
(plant, waste dump and tailings dam).
At Arqueros, 50 metallurgical samples were collected
from RC chips, diamond drill core and underground
workings for continued recovery testwork as part of the
de-risking of the project. Samples are now being
collected from Teterita to be dispatched for testing.
Resource drilling at Teterita was completed with 4,354
metres drilling (reverse circulation and diamond) in 43
drill holes.

With the completion of Teterita resource modelling, the
contained silver has increased by 30% to over 17 million
ounces. The total Mineral Resource at Teterita is hosted
in 6 million tonnes of ore at an average grade of 89 g/t
silver (cut-off 22.5 g/t silver). At a gold/silver price ratio
of 45, this is equivalent to about 380,000 ounces of gold
(cut-off 0.5 g/t gold).
This resource is based on 2,364 metres of reverse
circulation (22 holes) and 1,990 metres of diamond drilling
(21 holes) by Laguna Chile, and 8,888 metres in 69 drill
holes by the previous operator, for a total of 11,252 metres
of drilling in 114 holes, and 7376 samples assayed.
The new Mineral Resource Estimate for Nueva
Esperanza, including Teterita, is 75.3 million ounces of
silver and 227,000 ounces of gold hosted in almost 30
million tonnes at 0.24 g/t gold and 79 g/t silver. This is
equivalent to 1.9 million ounces of gold at a gold/silver
price ratio of 45, or 85 million ounces of silver. |
Mine planning is currently underway, which will allow
the incorporation of Teterita into the feasibility study.
Fieldwork was planned to commence on Chimberos with
a Resource and validation drilling program to start in
April 2012. Unfortunately, severe winter storms have
delayed the program which is now scheduled to
commence in September 2012. This program will
provide an opportunity to upgrade and potentially
expand mineral resources at Chimberos into Measured
and Indicated categories. This will allow this deposit to
be brought into the commercial development for the
combined Nueva Esperanza project.
Feasibility Study
The feasibility study for Nueva Esperanza continues to
advance, with the final report for the Arqueros sector due
at the end of April 2012. With the inclusion of the Teterita
deposit into the feasibility study, the final bankable
document is now expected to be delivered in the
September quarter 2012.
The new integrated mine plan (Arqueros plus Teterita)
being prepared is expected to enhance the project by
putting low strip Teterita and Arqueros North into
production first with resulting financial benefits of
delaying a pre-strip at the larger Arqueros South orebody.
Environmental Licensing & Community Consultation
The application for the environmental mining license is
being assessed by the authorities in Chile. Finalisation is
expected between September and December 2012.
REGIONAL EXPLORATION – AUSTRALIA
Wynberg (100%)
All approvals were finally received and a drilling program
has commenced at Wynberg in the Cloncurry district of
Queensland. This drilling campaign is designed to test
the potential for depth and strike extensions of a wellmineralised
gold and copper system that remains open
from limited historical drilling. |
