The Main Ridge Project surrounds the past producing Pennants Gold Mine (closed 2004) on three sides. Epithermal gold and copper/silver systems have been mapped over a 4km area, including rock chip samples of up to 35.8 g/t gold and channel samples of 1.22% copper and 7.8 g/t silver. Main Ridge is located along the Crawle River Fault Zone. It is contiguous to the west of C3 Metals’ Arthurs Seat mineral concession. A drill permit application has been submitted.
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 20 million ounces of gold reserves (Barrick Gold Corp. website as at March 31, 2023).
Exploration and prospecting, namely soil sampling and limited prospecting by BHP and others, during the 1990s demonstrate the excellent potential at Main Ridge 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. Main Ridge surrounds the past producing Pennants Gold Mine (closed 2004) on three sides with a reported resource grade of 20.4g/t gold.
Two mineralized structural corridors have been identified at Main Ridge, the Bennett Splay Fault Zone (gold) and Rio Minho Valley Splay Fault Zone (copper/silver).
Bennett Splay Fault Zone
Gold mineralization has been mapped over 4km along the Bennet Splay Fault Zone that runs through Main Ridge to the northwest of the past producing Pennants Gold Mine (closed 2004). Rock chip samples have returned multiple assays of over 1.0 g/t, including up to 35.8 g/t less than 1km from a historical drill hole that intersected 3.1m at 17.0 g/t gold but was never followed up on. Drill permit applications are in process for the Main Ridge mineral concession.
Rio Minho Valley Splay Fault Zone
Copper and silver mineralization is known to occur along the Rio Minho Valley Splay Fault Zone that runs through Main Ridge. Multiple rock chip samples have assayed over 2.0% copper and up to 18.5% copper. Discontinuous channel sampling over a 4km area along the Rio Minho Valley Splay Fault Zone has 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
- 2.0m @ 6.07% Copper + 19.4g/t Silver and
- 2.0m @ 1.92% Copper + 8.1g/t Silver
- 6.0m @ 2.0% Copper
- 6.0m @ 1.6% Copper
BHP discovered a 6km 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 at 20.4g/t gold2 small mining operation. The Pennants gold deposit remains 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 Splay Fault Zone within 2km from the Pennants Gold Mine and Main Ridge including:
- 3.1m at 17.0 g/t gold
- 3.0m at 7.7 g/t gold
- 2.2m at 3.0 g/t gold and 22.9 g/t silver
At the past producing Pennants Gold Mine, a single epithermal vein with an estimated true width of 3.0m to 5.0m was mined until 2004. Assays from Pennants’ drilling core commonly exceeded 10.0 g/t gold.

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.
