The Main Ridge Project (MRP) consists of a wholly-owned Special Exclusive Prospecting License (SEPL) covering 30 sq. km. MRP is located within the west-central part of the highly tectonized altered and mineralized Cretaceous Central Inlier. Europeans mined placer gold in the 16th Century within the Central Inlier. Grass roots exploration including sampling and mapping have been completed to date at the MRP.
The geologic history of subduction, crustal thickening and tectonism has produced extensive mineralization within areas of Cretaceous rock throughout the Caribbean, such as at the Pueblo Viejo deposit, which contains more than 36 million ounces of gold and 930 million pounds of copper.
Exploration and prospecting, namely soil sampling and limited prospecting by BHP and others, during the 1990s demonstrate the excellent potential at MRP for economically-viable epithermal gold and gold-copper porphyry and oxides deposits. A Canadian International Development Agency (CIDA) stream sediment sampling program indicates the presence of gold and copper in the Main Ridge area. The MRP surrounds the former Pennants Gold Mine with a reported resource grade of 20.4g/t Au
Two mineralized structural corridors have been identified at the MRP, Bennett Gold Zone (BGZ) and Rio Minho Valley (RMV)
Bennett Gold and Silver Zone
Gold mineralization concentrated along dilatational jogs, with recent grab samples (selected samples that are not necessarily representative of the mineralization hosted on the property) assaying up to
- 19.3g/t gold at Mango Valley
- 12.0g/t gold at Donkey Hill
- 1.7g/t gold at Silver Fish
Rio Minho Valley Copper and Silver Trend
- Channel sampling at the Cobre Verde prospect returned:
- 16.0m @ 1.22% Copper + 7.8g/t Silver
- Including 8.0m @ 1.61% Copper + 10.5g/t Silver
- Including 4.0m @ 2.21% Copper + 15.8g/t Silver
- Channel sampling at the Lime Valley prospect returned:
- 2.0m @ 6.07% Copper + 19.4g/t Silver and
- 2.0m @ 1.92% Copper + 8.1g/t Silver
- Channel sampling at the Trout Hall prospect returned:
- 6.0m @ 2.0% Copper
- 6.0m @ 1.6% Copper
BHP discovered a 6 km structurally-controlled gold in soil anomaly in the 1980s. This anomaly led to the discovery of the Pennants Gold Mine, a high grade 75,535t @ 20.4g/t Au small mining operation. The deposit at Pennants is open at depth and along strike. A number of historical intersections of veins have been reported on the licence from near the eastern end of Bennett Gold Zone: 7.7 gAu/t over 3.0m from one hole; 3.0 gAu/t over 2.2m and 22.9 gAu/t over 2.0m from a second hole: and 2.0 gAu/t from a third hole. At the former Pennants Gold Mine, values of 3.0m to 5.0m true width from drill core, commonly assayed from 6.0 – 8.0 gAu/t, frequently exceeding 10.0 gAu/t.

2 The mineral reserve cited above is presented as a historical estimate and uses historical terminology which does not conform to current NI43-101 standards. A qualified person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves. Although the historical estimates are believed to be based on reasonable assumptions, they were calculated prior to the implementation of National Instrument 43-101. These historical estimates do not meet current standards as defined under sections 1.2 and 1.3 of NI 43-101; consequently, the issuer is not treating the historical estimate as current mineral resources or mineral reserves.
3 Data from the above drill results are historical results and it is unknown what type of quality-control programs were performed at the time. The QP also advises that true width of the above results cannot be determined at this time.
