Point Location Description: Precise
Location Method: Conversion from MDI
Access Description: The Pathfinder Prospect is located on claims K.735068, K.777190 and K.850268 (former mining locations A.D.68, A.D.72, A.D.89) in Concession l. Lots 9 and 10, Melgund Township. The property is accessible by the Melgund 8C gravel road which branches west from the Sandy Point Road, 5.3 km south of its intersection with Highway 17 at Borups Corners. A very rough, narrow, bush road branches north from the Melgund 8C road, 1.3 km west of its intersection with the Sandy Point Road. The bush road continues north for about 1.5 km and leads directly to the property.
1945: Pathfinder Syndicate sampled the property and conducted diamond drilling. Shafts were sunk on the property prior to 1945. 1984: Staked by A. Glatz. 1985: Transferred to Sulpetro Minerals Ltd., who conducted sampling, geological mapping, and diamond drilling. 1986: Transferred to A. Glatz.

Aug 03, 2022 (Q Unknown) - The Pathfinder Prospect is underlain by massive, fine- to medium-grained, chloritic, mafic, metavolcanic flows intercalated with intermediate and felsic tuff, and lapilli-tuff and intruded by felsic dikes. Two shallow shafts and several trenches have been sunk on quartz veins in intensely sheared and altered mafic rocks. The prospect is 4 km west of the contact between the Revell Batholith and the metavolcanic rocks.

Aug 03, 2022 (Q Unknown) - Shaft No. 1 is located immediately next to a large mud flat and has been sunk on a shear zone striking 038°-042°/75° SE and hosting a 0.3 m wide quartz vein containing iron carbonate and variable amounts [<1%-5%] of pyrite. Mafic metavolcanic wall rocks are intensely iron carbonatized and contain abundant coarse-grained, pale green fuchsite. The metavolcanics near the shaft consist entirely of fuchsite and iron carbonate. The shear zone has been intruded by massive, intensely altered felsic dikes which have not been sheared. The orientation of the shear zone changes to 084°-088° in a test pit approximately 9 m north of the shaft. Although alteration is very intense, it is not extensive, and consists of a 30 m to 46 m wide zone. Shaft No. 2 is situated north of shaft No. 1 and has been sunk on a shear zone striking 048° and hosting a boudinaged, milk white quartz vein with a maximum width of 0.6 m. The host rock is a small gabbro intrusion or coarse-grained flow which has been chloritized, carbonatized (calcite), and contains abundant disseminated magnetite, and specular hematite on fracture surfaces. The gabbro has intruded fine-grained mafic tuffs and flows. The quartz vein and wall rocks contain <1% pyrite. Alteration is confined to the immediate sheared wall rocks and is not as intense as the alteration at shaft No. 1. Sulpetro Minerals Limited sampled the prospect and obtained low anomalous gold values with some erratic high grade values (Assessment Files, Resident Geologist's Office, Kenora). Twelve grab samples taken from the property by the Pathfinder Syndicate assayed between 0.10 ounce gold per ton and 1.24 ounces gold per ton with consistent high values. A chip sample reportedly assayed 1.14 ounces gold per ton across 1.0 metre. The Pathfinder Syndicate also drilled twelve holes on the property (Assessment Files, Resident Geologist's Office, Kenora).
