Point Location Description: Assessment report 42C14NW2005

Location Method: Based on Assessment

Access Description: Access to the southeastern and southern portions of the property is via a network of Domtar logging roads beginning approximately 70 km south near the town of White River. The road network begins with Domtar Road 100 at the Domtar Mill on Highway 17 and leads north to Domtar Roads 135, 400, 403, 403-130, and 403-134, respectively.

Exploration History

1984: Golden Rule Resources Ltd. flew airborne magnetometer, EM, resistivity, and VLF-EM surveys. 1989: Noranda Exploration Co. Ltd. flew helicopter-borne magnetometer and EM surveys. 1998: J. Ternowesky, W.L Cox, and L. Halverson staked 7 claims along the southeastern margin of the Bulldozer Mafic-Ultramafic Complex. 1999: The Silver Fox Copper occurrence and several other sulphide occurrences were discovered during an exploration program that included linecutting, ground magnetometer and VLF-EM surveys, and limited prospecting. Gryphon Metals Corporation optioned the property a short time later and staked another 12 claims to the west of the existing claims. 2000: Gryphon completed a magnetometer survey. Gryphon subsequently optioned the property to Freewest Resources Canada Inc. who then completed prospecting and geological mapping. 2005: North American Palladium Ltd. flew a VTEM geophysical survey, and carried out prospecting and sampling. 2019: Palladium One Mining Inc. carried out prospecting, sampling, and soil sampling. 2021: Palladium One flew an airborne VTEM and magnetic survey.

Geology Comments

Apr 20, 2016 (Therese Pettigrew) - The Silver Fox Copper occurrence is located near the northern margins of the large Black-Pic Batholith of the eastern Wawa Subprovince, Superior Structural Province. The rocks within this portion of the Subprovince have not yet been mapped by the OGS or GSC. The composite Black-Pic Batholith is a foliated to massive, tonalitic to granodioritic structural dome intruded by late gabbro, diorite, granite, and granodioritic complexes and plutons. It is characterized by a low to moderate intensity, relatively uniform magnetic signature and is bound by the moderately to strongly magnetic Manitouwadge-Hornpayne greenstone belt to the north; the variably magnetic, eastern Schreiber-Hemlo greenstone belt and the roughly circular, very strongly magnetic Coldwell Alkaline Complex to the south, and the Dayohessarah-Kabinakagami greenstone belt to the east. The Bulldozer Mafic-Ultramafic Complex is readily visible on airborne magnetic maps as a large (10 x 7 km), strong, elliptical anomaly with a north-trending, western apophysis. All rock-types in the region are cross-cut by numerous, moderate to strong, linear, magnetic anomalies generally representing Paleo-Proterozoic, quartz and locally olivine diabase dykes of the NW-trending Matachewan (2454 Ma) and NE-trending Marathon (2170) swarms. Many of these dykes occupy pre-existing faults (AFRI 42C14NW2005).

Mineralization Comments

Apr 20, 2016 (Therese Pettigrew) - The Silver Fox Occurrence (L4+50N), 12+10 W) is located 1540 m WNW of the Bulldozer Occurrence. The mineralization is patchy and occurs within locally rusty, biotitic hornblendite to hornblende melagabbro and consists of trace to 5% finely disseminated pyrite and chalcopyrite. The host-rocks are locally brecciated and intruded by leucotonalite veins and dykes. Eight grab samples were taken. Only Cu occurs in any significant amounts, ranging from 123-2276 ppm, with the precious metals are generally below detection limit. A few samples contain high background to slightly anomalous amounts of Pd (18-40 ppb) (AFRI 42C14NW2005). Soil sampling conducted by Palladium One in 2021 on the Bulldozer South anomaly returned up to 891 ppm copper and 142 ppm cobalt. The soil samples have similar metal ratios compared to the historic Bulldozer showing suggesting a similar mineralization style (Palladium One June 9, 2022 press release). Grab sample 470459 collected in 2019 returned 594 ppm Cu and 632 ppm Ni (Assessment report 20000018199).
