Roger’s Creek

 

SUMMARY

The Rogers Creek project straddles the Lower Lillooet River Valley, approximately 90 kilometres northeast of Vancouver, and 28 kilometres south of Pemberton. The project consists of 47 contiguous claims, aggregating 212.34 square kilometres. Rogers Creek is under option to Tocvan Ventures Corp, where they can earn 80% of the project by spending $1.8M and issuing C3 Metals 1M shares over 4 years. The Rogers Creek property consists of four significant target areas including a minimum 6 x 2 km area of anomalous soil geochemistry, multiple untested IP anomalies, and significant surface exposures of copper, gold, and silver mineralization.

GEOLOGY

The property is centred on the Miocene-aged Rogers Creek Intrusive Complex (16.7+/-2.7 Ma), which intrudes overlying and coeval Miocene-age Crevasse Crag volcanic flow rocks and pyroclastic rocks, and older metamorphosed Jurassic and Cretaceous host rocks. Although the Rogers Creek Pluton is dominantly granodioritic, the western contact of the pluton comprises a porphyritic, intermediate contact phase, and discrete feldspar-, biotite-, and hornblende-phyric syenitic bodies. Syenite, diorite, porphyritic granodiorite, and monzonite phases have also been mapped.

POTENTIAL

C3 Metal’s interpretation of the magnetic signature  in the northern half of the property is an oval-shaped eroded caldera cored mainly by various dioritic to granodioritic intrusives that are cut by multiple generations of arc-parallel and related conjugate fault sets. These faults are interpreted to have focused the emplacement of a post-mineral intrusive breccia at the core of Target I and likely gave rise to the formation of the magnetic low at the core of Target II. The formation of these faults also directly controlled multiple stages of copper-gold +/- molybdenum mineralization across at least the northern half of the property especially in and around the margins of Targets I and II magnetic lows.

Recent Results

Throughout 2015 and 2016, a six line-kilometre IP survey was completed within Target 1, complimented by additional analysis of soil samples from storage to define the northern limits of the system. After processing of the IP data, it was discovered that a large, open ended chargeability anomaly occurs within the northern section of Target 1. A full compilation, integration, and modelling of all data was placed in 3D software for future targeting.

In 2019, Tocvan Ventures completed their first year of exploration which included extending the IP survey further north.  Results from this survey confirm the location of the chargeability anomaly and better defines a compelling drill target.

PREVIOUS EXPLORATION

In 2008, the company conducted a major field program including a 1,506 line-kilometre airborne magnetic survey, which was flown over the northern two-thirds of the property. In 2010, an airborne magnetic and radiometric survey was flown over the southerly Fire Mountain claim block. Results of the two airborne surveys, and field work consisting of stream sediment and soil sampling, prospecting, and mapping in 2008 and 2009 defined the four target areas. A 28 line-kilometre IP survey completed over Targets I and II in 2009 and helped to focus an initial three-hole drill program on the western margin of Target I that was completed in the fall of 2009.

Streams draining Targets I and II returned silt samples containing up to 800 ppb gold, 835 ppb silver and 73 ppm copper versus background values of approximately 2.5 ppb gold, 20 ppb silver and 15 ppm copper. Quartz-sulphide veins on the periphery and cutting Target I breccia returned gold and silver values up to 23.1 g/t gold, 232 g/t silver, 0.69% copper and 81.4 ppm molybdenum. The strong stream and rock geochemistry is reflected in the broad distribution of gold (>25 ppb Au) and copper (>100 ppm Cu) soil anomalies within the 6 x 2 kilometre area encompassing Targets 1 and II and to a lesser extent Target III, which has a dominant gold signature.

Mapping, prospecting, and surface sampling within the Target II soil geochemical anomaly located copper-gold mineralization within an 80 x 100 metre area. The mineralization, hosted by silica-chlorite altered hornblende diorite, consisted of up to several percent disseminated chalcopyrite and lesser pyrite with rare chalcopyrite and pyrite veins up to one cm wide. An initial 10 grab samples, excluding one cross-cut by a pyrite-chalcopyrite vein which returned 3.72% Cu, 15.75 g/t Au and 91.9 g/t Ag, averaged 1.372 g/t Au, 0.53% Cu and 11.97 g/t Ag. Highlight samples included:

Channel sampling of the surface mineralization returned 9.12 metres of 1.96 g/t gold (“Au”), 0.57% copper (“Cu”) , 13.7 g/t silver (“Ag”) confirming the results of the grab samples.

A total of 10 holes for 5,200m of core drilling has been completed at Rogers Creek with anomalous gold and copper intersected in all holes.
