- Acquired by Golden Sky Minerals in 2023 through staking. The Project is 100% owned by Golden Sky with no underlying royalties
- Large ~26,300-hectare consolidated land package overlying the Auden Structural Zone, which is a significant east-west trending fault interpreted to be an eastward extension of the Beardmore-Geraldton gold producing structural system
- Located in a Tier 1 Mining District with a similar geological setting to Equinox/Orion’s Greenstone Gold Mines (5.05 Moz Au), Agnico Eagle’s Detour Lake Mine (20.6 Moz Au) and other orogenic camps such as Timmons and Kirkland
- Historical exploration has proven gold mineralization with just 58 drillholes spread out over ~70 km
- Many geophysical targets remain untested and known gold occurrences remain open in all directions
- Very cost-effective exploration with nearby infrastructure that includes an extensive backroad network branching off of paved Highway 11, electric power grid, regional railway and local accommodation in Hearst, Ontario, located 60 km to the southeast
- The Auden property lies at or near the boundary between the Wabigoon and the Quetico Subprovinces and based on government published airborne magnetic geophysical maps, it is interpreted that the Auden property likely covers an eastern extension of the Beardmore-Geraldton Greenstone Belt, which is documented ~100 km to the west. Importantly, the significant east-west trending Beardmore-Geraldton structural system is also interpreted to extend onto the property and is locally termed the Auden Structural Zone.The property is primarily underlain by an easterly trending sequence of mafic metavolcanics, metasediments, quartz porphyry and iron formation. These rocks are Precambrian in age and have been regionally metamorphosed to mid greenschist faces and locally amphibolite facies. A thin veneer of shallow, north dipping Paleozoic sediments covers the Archean rocks in parts of the eastern block of the property.The historical drilling on the property has demonstrated that encouraging gold mineralization is known to occur over the entire ~70 km strike-length. Results from historical drill records indicate that gold mineralization occurs on the Auden Project in a variety of geological settings. Previous exploration has identified gold mineralized associated with sulphide facies iron formation, silica facies iron formation, quartz-carbonate-tourmaline veining within mafic volcanics and volcanic tuffs, metasediments mineralized with pyrite and pyrrhotite and conglomerated mineralized with pyrite and pyrrhotite.
Selected Historic Exploration Highlights:
- District-scale opportunity with 26,300 hectares that covers a ~70 km strike-length of the Auden Structural Zone, which has historically been interpreted to be an extension of the Beardmore-Geraldton structural system. The zone remains largely untested despite anomalous gold values being recorded from drilling and surface rock samples.
- Due to extensive overburden cover in the region (<5% outcrop), past operators relied heavily on geophysical survey results followed by early-phase exploration drilling with widely-spaced holes over several kilometers. Within the property area, 58 historical drill holes have been recorded. These early drill programs were typically limited to following up on ground-based geophysical targets, as the first large-scale airborne geophysical survey was not conducted until 1993. Though limited in scope, the drilling successfully demonstrated that precious metal mineralization is associated with a major east-west oriented structure that extends ~70 km (Auden Structural Zone).
- Some of the earliest recorded drilling was by the Fatima Mining Company Ltd. from 1956 to 1958. These holes are located in the western portion of the property. A total of 20 drill holes were spaced over 15 km of sheared and folded metasediments, quartz porphyry and iron formation. Almost every hole intersected zones of carbonate alteration, quartz veining, and semi-massive to disseminated sulphides. There is no report of gold assays, as the focus was on base metals. In 1990, McKinnon Prospecting conducted a field visit that included reanalysis of a few samples of Fatima Mining’s core. One sample of semi-massive coarse-grained pyrite-pyrrhotite mineralization assayed 367 ppb gold and 250 ppm arsenic, which highlights the prospectivity for gold mineralization in the area.
- In 1965, Colleen Copper Mines Ltd. explored around the Nagagami River in a zone of metavolcanics, conglomerate, iron formation and quartz porphyry with semi-massive to disseminated sulphides. A grab sample assayed 25 g/t Au and 2.36% Cu (unverified). A follow-up 4-hole drill program that focused on base metal exploration disclosed only two reported assays, both from Hole CC4 (0.41% Cu over 1.5 m and 0.1% Cu over 1.5 m).
- From 1976-1978, Shell Canada Resources Ltd. conducted a regional program but never filed this work for assessment credit. Shell successfully delineated a regional structure that was later termed the Auden Structural Zone. An estimated 12 holes were drilled in the region; in spite of strong alteration and the presence of arsenopyrite-pyrite-pyrrhotite mineralization, no assay results were recorded. In 1993 McKinnon Prospecting compiled the Shell data and collected 48 samples to analyze for gold and arsenic. The gold assays ranged from 19 ppb Au to 1,277 ppb Au. In drillhole S78.04, one section of highly deformed pyrrhotite-rich, arsenopyrite-bearing iron formation assayed 0.670 g/t Au over 16.9 m.
- The most recent significant exploration occurred from 1988-1993 by McKinnon Prospecting, who was the first to conduct a comprehensive, property-wide airborne VLF-EM geophysical survey which highlighted 34 target areas. A follow-up 17-hole drill program provided critical insight into the geology of the region and either extended or discovered several strongly altered shear zones with anomalous precious metal values. One of the most compelling magnetic and electromagnetic (EM) geophysical targets was tested by holes MP-17-1, MP-14-1 and MP-13-1, collared at multi-kilometric intervals along an 8-km east-west trend. The most westerly hole, MP-17-1, intersected a 27 m wide zone of pyrrhotite-rich iron formation that was selectively sampled, returning encouraging assays of 3.33 g/t Au over 1.2 m, 1.22 g/t Au over 1.5 m, and 1.54 g/t Au over 0.7 m. Hole MP-14-1 was collared 5 km to the east and intersected anomalous gold values over several metres, with the highest value of 0.8 g/t Au over 1.3 m. Hole MP-13B-1 was collared 2.7 km east of MP-14-1 and returned an assay of 0.19 g/t Au over 0.95m. These 3 holes intersected similar geology over ~4.2 km. The continuity of these rock units is further supported by airborne magnetic geophysics, which highlights the potential for further exploration along this trend.
- Nearby infrastructure includes an extensive back-country road network, electric power grid, paved Highway 11, rail access, and local accommodations in Hearst, Ontario (2021 pop: 4,794), located 60 km to the southeast. These factors support very cost-effective exploration.
