Latitude: 49° 48' 10.96" Longitude: -91° 18' 48.53"
UTM Zone: 15 Easting: 621358 Northing: 5518097 UTM Datum: NAD83
Resident Geologist District: Kenora
NTS Grid: 52G14SW
Point Location Description: DDH STK-006 from Assessment report 20000003141
Location Method: data compilation
Access Description: Access is via Highway #599 north from Ignace for 55 km to Silver Dollar, then west along Highway #642 for 11 km. At this point a small logging road is used to access an old railway grading which transects the property from northwest to southeast corners, between Stake and Moss Lakes.
2006: Benton Resources carried out prospecting and sampling. 2007: Tri Gold Resources optioned the property and carried out IP and magnetic surveys, trenching, sampling, and drilled 6 DDH totalling 1398.5 m.

03/07/2011 (C Ravnaas) - The oldest rocks shown on these maps are fine to medium grained mafic volcanic, flows (mostly massive), with rarer tuffs and agglomerates paralleling a weak 070 deg foliation. This is the predominant rock type shown to underlay the central portion of the claims where the drilling occurred. The next youngest rock type is the “multiphase, differentiated” mafic to ultramafic Pike Lake Intrusion. This lithology is shown to occur in the southwest corner of the claim block, about 1 km southwest of the area of drilling, and along the eastern margin of the property. Foliation and overall morphology parallels the 070 deg fabric of the mafic volcanic rocks. The youngest rock type shown on regional maps to occur in the property area is the Granodiorite to Trondhjemitic Shanty Lake Intrusion, which is indicated as covering the northern three claim blocks.
Rock Type | Rank | Composition | Texture | Relationship |
---|---|---|---|---|
mafic metavolcanics | 1 | |||
intermediate metavolcanics | 2 | granodiorite to monzodiorite |
03/07/2011 (C Ravnaas) - Four main rock types were encountered in the drilling. 1 - Basalt is a typical “greenstone”, massive to weakly, sub-vertically foliated, with very rare amygdaloidal, tuffaceous, sandy, calc-silicate or cherty bands. 2 - Granodiorite is medium grained, homogeneous, equigranular and consists of 30% Quartz, 60% Feldspar, and about 10% mafic mineral. Alteration is ubiquitous consisting of weak albitization of feldspars, and partial chloritization of mafics. 3 - Monzo-Diorite is medium grained, massive, and consists of 5-10% Quartz, 50% feldspar, and 30% chlorite altered mafic mineral. This may the Trondhjemite indicated on regional maps. 4 - Less abundant rock types include Mafic and Felsic Dikes. Mafic Dikes are massive, black, very hard, aphanitic, contain no sulphides, and have sharp contacts (occasionally chill margins) and cut all other rock types. Felsic dikes are massive, very light tan or grey, very hard, aphanitic, have very sharp contacts, and contain 1% very finely disseminated pyrite and pyrrhotite. They occur only within the basalt.

03/07/2011 (C Ravnaas) - Sampling of large angular float yielded up to 4.16% Cu, 82 ppm Ag, 2,755ppb Au, with elevated Zn. Additional sampling of the boulders by geologist's office staff yielded up to 42 ppm Ag, 2500 ppm Cu, and 656 ppm Zn. Tri Gold Resources between August 14th and August 29th, 2007 drilled 6 holes totalling 1,398.5 m. This drill program was not successful in locating the bedrock source of the boulders by did intersect gold and copper mineralization. The highest values from this drill program were 1126 ppb Au, 4943 ppm Cu and 463 ppm Ni. The felsic dikes intersected in the drill holes all have elevated Cu/Au values, and the highest Au sample of the program 1126ppb occurs in a one of these near the bottom of hole STK-005.

02/12/2020 (T Pettigrew) - DDH STK-006 returned up to 4943 ppm Cu and 0.168 ppm Au over 0.3 m from a monzodiorite with chalcopyrite in vuggy stringers. DDH STK-005 returned up to 2035 ppm Cu over 0.75 m from a mafic metavolcanics with pyrrhotite and minor chalcopyrite, and 2489 ppm Cu and 0.126 ppm Au over 0.3 m from a basalt with pyrite and chalcopyrite. DDH STK-002 returned up to 3343 ppm cu and 0.173 ppm Au over 0.3 m from a basalt with chalcopyrite (Assessment report 20000003141).
