Early Discoveries of Silver, Zinc and Lead Require More Exploration
The Cabin property is located in central British Columbia approximately 22 km southwest of Fraser Lake and 145 km west of Prince George within the historic Omineca Mining District. Other notable projects in the area include Centerra Gold’s Endako Mine which lies 17 Km to the north and New Gold’s Blackwater project located approximately 80 Km to the south. The property is attractively located and is near infrastructure, the terrain is characterized by rolling hills and is accessible by road and has access to low cost hydroelectric power. The Cabin property is situated approximately 15 Km east of Gray Rock’s GSLT property and 40 km north of Gray Rocks Ootsa property.
Historic drilling and sampling programs, while extremely successful in providing geologic insight, did not target areas of highest potential to intercept mineralization. For this reason, and with the target an Epithermal Au-Ag with low sulphidation, an extensive exploration program is recommended.
In 1964, local prospector Whitney Foote from Fraser Lake, BC discovered significant silver, lead and zinc in float samples from the Cabin Lake area. Foote staked claims in the area and further geochemical work produced encouraging results. Later in the year R & P Metals drilled six holes without performing significant groundwork. Drilling results are not available.
According to and assessment report filed with BC’s Minestry of Energy and Mines, drilling in 1972 intersected mineralization in several holes of which the best was 0.65 metre at 2714.98 g/t silver, 8.6 per cent zinc and 5.05 per cent lead
In 1976 Nithex Exploration Ltd. performed detailed soil and rock geochemistry, magnetometer and electromagnetic surveys within a historic property-scale grid system, soil sampling revealed several associated silver, lead and zinc anomalies and were left open to the east, north and south.Later in the year, Nithex drilled six percussion holes to a maximum depth of 100m. Drilling results proved the validity of electromagnetic and geochemical anomalies One of the 6 holes had a 70-ft intercept of 1.16 Oz/t Ag & 1.07% Zn. A second hole had a 10 ft intercept of 2.82 Oz/t Ag & 2.65% Zn.
Despite promising results from geochemical and geophysical surveys and drilling undertaken by Nithex, the area did not see any further development until acquisition by BP Resources Canada Ltd. – Selco Division (BP), who completed 675 soil and chip samples in 1984. Results from sampling led to discovery of mineralising potential to the south and confirmed base metal anomalies to the northwest of Cabin Lake.
Following BP Resources Canada Ltd. ownership, Nation River Resources Ltd. acquired the Cabin claims and in 2000 drilled two short XRT diamond drill holes with anomalous results in silver, lead, zinc and molybdenum, and in 2002, one BQ drill hole to 94.7 metres, then in 2005 eight trenches totaling 387 cubic metres were completed.
In 2010, Paget Resources Ltd. optioned the Cabin claim group and later drilled seven holes targeting mineralized fault structures at depth. Little public data exists for work completed on the Cabin claims between 2000 and 2010.
In 2012, RebelEx Resources Corp. collected a total of forty-five grab samples, fourteen soil samples and one stream sediment sample in addition to generation of a geological map and detailed petrographic analysis of five representative rock samples. During 2012 mapping and sampling activities, several new mineralised zones were discovered while the West and Central Zones were expanded both along strike and perpendicular with known mineralized structures.
The Cabin Lake property is underlain by lower to Middle Jurassic volcanosedimentary rocks of the Hazelton Group to the east, Late Cretaceous andesite belonging to the Kasalka Group to the west, Eocene Endako Formation andesite to the south and quartz monzonite of the Late Cretaceous Cabin Lake pluton centered within the claim group.
The primary geological target is epithermal veins, shear‐zone hosted gold deposits. “Epithermal” literally means “shallow heat”, and is applied to hydrothermal systems emplaced at shallow depths (<1 km) in the earth’s crust. “Low Sulfidation” refers to a style of epithermal system developed in a geothermal or hot springs environment. Gold and silver mineralization in low sulphidation epithermal vein deposit (“LSEVD”) systems occurs dominantly as veins and stockworks with minor disseminations. Low‐sulfidation deposits form from neutral‐pH, reduced (H2S‐rich) hydrothermal fluids similar to those encountered in geothermal systems with surface manifestation including silica sinter‐depositing hot springs and steam‐heated acid‐sulfate alteration.
