Cochrane Hill Gold Project
|
Introduction
As an augmentation to Touquoy throughput our preliminary financial assessment of Cochrane Hill, with a current resource
inventory of 547,000 ounces gold, indicates that a very attractive profitable return can be realised. |
| The total Indicated and Inferred Resources were upgraded in September 2009 to
10.1 million tonnes at an average grade of 1.7 g/t, for 549,000 contained ounces of gold. |
| Excellent results have been received from the first stage of a 5000 m resource
development diamond drilling program with shallow open pittable mineralisation intersected over substantial widths, up to
31 m at 2.43 g/t from 19 m depth. |
Purchase of 100% of Cochrane Hill Gold Project
Atlantic Gold, through its wholly-owned Canadian subsidiary DDV Gold Limited, entered into an Option Agreement on the
Cochrane Hill advanced exploration property with TSX-listed Scorpio Mining Corporation (Scorpio) in May 2007.
|
|
In May 2011, Atlantic Gold entered into a formal agreement with Scorpio to purchase 100% interest for C$1.6 million. Scorpio's offer
was made in accordance with Atlantic Gold's pre-emptive rights under the Option Agreement, Scorpio having received this offer from a
third party, Steeple Holdings Limited (Steeple). Steeple sought an order from the Supreme Court of Nova Scotia claiming that the
Cochrane Hill property should have been sold to Steeple. Their application was declined and subject to any appeal, the acquisition of
100% of the Cochrane Hill gold property by Atlantic Gold can now proceed.
|
Location
The property comprises 53 mineral claims (8.3 square km) and is located 80 km east of ATV's Touquoy Gold Project.

Mineral Resources
The Mineral Resource estimate for the Cocrahen Hill Gold Project, prepared by resource estimation specialists
Hellman & Schofield in September 2009, increased
Indicated and Inferred Resources at Cochrane Hill to 10.1 million tonnes at 1.7 g/t, for 549,000 contained ounces of gold.
This estimate incorporates results from the 39 diamond holes (3,102 m) having now been drilled into the resource by
Atlantic Gold as well as a substantial amount of additional gold data sourced from assaying of 3100 m of previously unassayed
intervals of historic drill core recovered from storage in the Nova Scotia Department of Natural Resources' core library.
This revised resource figure adds to the 656,000 ounces of contained gold already estimated at Atlantic Gold's Touquoy
Gold Project, 80 km west of Cochrane Hill. It lifts the total contained gold controlled by the company in Nova Scotia to
1,205,000 ounces.

Since the original assaying during the 1970s and 1980s had been selective with
un-assayed intervals having been ascribed zero grade, about 3100 samples of previously un-assayed core have been submitted
for gold assay. By simply "filling in the blanks" - no re-assaying of core previously assayed has been conducted - results
for the holes tested averaged about a 25% increase in grades to those applied in the above resource estimate.
Notwithstanding the relatively high proportion of Inferred Resources in the total Cochrane Hill resource inventory,
a preliminary scoping study using Touquoy mining and plant throughput costs and estimated haulage costs indicates a very
attractive return. Refinement of the input parameters from resource delineation and estimation, metallurgical recovery,
pit design through to haulage, processing costs and so on is therefore now a key priority.
Excellent results have been received from the first stage of a 5000 m resource development diamond drilling program
with shallow open pittable mineralisation intersected over substantial widths, up to 31 m at 2.43 g/t from 19 m depth.
These results are a further step towards confirmation that the Cochrane Hill gold deposit, developed in synergy with
Touquoy, will be commercially viable with real potential for over 900,000 ounces of gold to be produced from these two deposits.
Conceptual study level modelling has been completed based on a unified production plan for the Touquoy and Cochrane Hill
Gold projects. This unified production scenario, which involves relocation of the Touquoy 2 Mtpa gravity/CIL treatment plan
to Cochrane Hill following completion of the Touquoy operation, presents a potential 90,000 ounces per annum production plan
over a 10 year mine life. |
Geology
Exploration potential beyond the area of the drilled resource is excellent. The sheared, mineralised sequence is parallel to,
and 100 m south of, the axis of the overturned Cochrane Hill anticline (refer to accompanying property plan). This intermittently
outcropping shear zone has been traced for 5 km across the property in previous exploration programs, and it hosts several
areas of anomalous gold geochemistry in various media. The most notable of these is a trench grading 1.9 g/t gold over 7.6 m
about 1.6 km west of the resource. No drilling has been conducted along this mineralised shear zone beyond that central
1200 m length encompassing the identified resource.

Exploration drilling
Fourteen fences of staged reconnaissance RC drilling (82 holes for 1246 m) have been drilled to investigate this mineralised
shear zone across the property beyond the limits of the main resource - eleven 100 m-spaced fences west of the
main resource and three 500 m-spaced fences east of the main resource (see accompanying plan). Gold mineralisation
indicative of the target zone has been recorded in all of the fences now drilled west of the main resource with the
distinctive Cochrane Hill-style quartz-veined and sulphidic lithologies recognised at two locales. At one of these,
impressive results - up to 12.2 g/t over 8 m from 4 m depth - were returned from section 2140E located 600 m west of
the main resource. |
|
Eight diamond core holes have now been drilled to follow up these RC results - six around
2140E and two on 1775E. Assay results for the first four of these holes have been received with best return of 1.2 g/t gold
over 6 m from 53 m in hole CH-08-006 on 1775E. Best result from the two diamond core holes drilled beneath the high grade
RC holes on 2140E was 4.3 g/t over 1 m. Assays from the remaining four diamond core holes are pending. |
|
Grade distribution evident within this extensive mineralised
zone suggests the high grade mineralisation on 2140E is disposed as a shallow-plunging high grade shoot, probably one of
several, within a halo of lower grade material. Further drilling is required to evaluate this mineralisation and to explore
the remainder of this attractive property.

Conclusion
Atlantic Gold looks forward to advancing this property towards production in the near term. It remains Atlantic Gold's
conviction that this gold district of Nova Scotia is highly prospective for major open-pittable gold resources similar
in style to those at Touquoy and Cochrane Hill. Ongoing exploration for such deposits and development of these two Projects
are the forward steps in Atlantic Gold's strategy to develop a robust and environmentally sustainable gold mining industry
in Nova Scotia. |
