Prospect Ridge Resources Corp. (CSE: PRR) (OTC: PRRSF) (FRA: OED) has returned assays up to 21.3 grams per tonne gold, 38.3 grams per tonne silver and 1.6% copper from grab samples and 12 grams per tonne gold over a one-metre chip from recent exploration at the 4shore zone on the Holy Grail property in British Columbia.
The 4Shore zone is located in the central-west part of the Holy Grail property. The area is underlain by deformed volcanic and tuffaceous units of the Hazelton group. This is one of the most prominent mineral-rich, rock packages in the Golden Triangle, hosting deposits such as Eskay Creek, which produced 3.3 million ounces of gold and 160 million ounces of silver at average grades of 45 g/t gold and 2,224 g/t silver.
In effect, the 4Shore zone was targeted as a high priority area as the ‘Quock’ formation, part of the Hazelton group is a stratigraphical marker horizon for the Eskay Creek deposit and strikes north west through the 4Shore zone.
Initial results have produced up to 21.3 grams per tonne gold, 38.3 grams per tonne silver and 1.6% copper from grab samples and 12 grams per tonne gold over a one-metre chip, with various mineralised exposures over an approximately 400m wide zone across strike. Reconnaissance approximately four km down strike to the southeast discovered malachite staining that could be observed for hundreds of metres vertically and laterally and is cross cut by high grade sulphide-rich quartz veins. Assays are pending for this southeast extension.
Mineralisation in the 4Shore zone is unique, discrete and different from the other areas on the Holy Grail property. The tuffaceous units are highly deformed, folded and altered to a chlorite-muscovite schist. The mineralisation is structurally related and lithologically-controlled. Three modes of mineralisation are apparent:
A) Disseminated mineralisation that formed prior to deformation and folding of the host rock
-Potentially related to pre-existing VMS-style mineralisation
B) Low angle shearing and remobilisation
-Concentrated and remobilized pre-existing mineralisation into more massive form
C) Typical high-grade epithermal to mesothermal quartz veining related to brittle faulting
-North-south trending paralleling major linears and cross-cutting existing mineralization
-Targeted style of mineralization on remainder of the Holy Grail property
In 2021, two ‘turn-of-the-century’ adits were rediscovered. A two-metre chip sample assayed 6 grams per tonne Gold was taken over a contact in the adit between a lighter and darker chlorite-muscovite schist unit with no obvious mineralisation. The former returned 0.017 grams per tonne and the latter 12 grams per tonne gold over one meter and remains open.
