Exploration History

1934: Dumond Mining and Exploration Limited discovered gold in sulphide-replacement lenses within iron formation approximately 200 m northeast of Nissiamkikam Lake (Mackasey 1976). 1936-37: development of a 100 m deep, three-compartment shaft (UTM Zone 16: 454618 E, 5504134 N) and diamond drilling by Oremond Gold Mines Limited. Two levels were established, at 45 m and 84.3 m. 1940: the original Solomon’s Pillars prospect was drilled by MacLeod-Cockshutt Gold Mining Limited; however, no records are available from this work. 1968: Solomon’s Pillars Mines Limited took ownership of the claims. The company completed a geological survey, drilled six holes totalling 247.2 m, dewatered the shaft and sampled the ore zone. 1969: Canadian Nickel Company Limited (Inco) re-staked the property and brought several claims to lease including TB 222656, which hosts the Solomon’s Pillars shaft and main exploration trenches. 1969-1988: Canadian Nickel completed approximately 7300 m of diamond drilling on the Solomon’s Pillars property. Very low frequency electromagnetic (VLF-EM) and magnetometer surveys, as well as geological mapping and sampling, were also performed during this period. 2007: The Solomon’s Pillars property was optioned by Kodiak Exploration Limited. 2008: Kodiak completed approximately 5000 m of drilling before returning the claims to 2090720 Ontario Inc. 2009: Sage Gold Inc. optioned the property and carried out mapping, sampling, extensive stripping and trenching, and the completion of 26 diamond-drill holes totalling 3777.5 m. This work uncovered the Royal Crown, Golden Sceptore, and Throne occurrences.

Geology Comments

Nov 15, 2011 (Robert Cundari) - The King Solomon’s Pillars property lies along the northern contact, and within the western part of the Southern Metasedimentary Sub-belt, which marks the southern boundary of the eastern Marmion Domain (formerly Wabigoon Subprovince) (Devaney and Williams 1989). As part of the Beardmore–Geraldton greenstone belt, the Southern Metasedimentary Sub-belt is host to 11 past-producing gold mines and over 95% of the 4.1 million ounces of gold produced from this greenstone belt (Mason and McConnell 1983). The Southern Metasedimentary Sub-belt (ca. 2691 to 2701 Ma), which averages 3 to 4 km wide across Walters Township, typically consists of arkose, wacke, siltstone, conglomerate and significant amounts of interbedded oxide-facies, banded iron formation (Devaney and Williams 1989). The clastic metasedimentary rocks and iron formation on the property are west-trending strike from 265° to 285°, and dip vertically to steeply south. Tops within this sequence young to the south, as indicated by graded bedding. The banded iron formation ranges up to 25 m thick in the shaft area and consists of fine-grained, laminated to thinly bedded red hematite, steel-grey magnetite, specular hematite and minor amounts of chert. Also noted along the western strike of the mineralized zone are several north-trending diabase dikes that cross-cut both the metasedimentary rocks and quartz-vein-bearing shear zones. The Watson Lake Fault, as described by Mackasey (1976), defines the contact between the metasedimentary rocks and the mafic metavolcanic rocks along the northern boundary of the property. The east-southeast-trending lineaments on the property reflect this structure.

Mineralization Comments

Jun 08, 2023 (Robert Cundari) - Exploration work conducted by Sage Gold Inc. on the King Solomon’s Pillars property during the fall of 2009 traced a gold-mineralized zone for almost 2.5 km west from the Solomon’s Pillars shaft. Three main occurrences (from east to west: Royal Crown (UTM Zone 16: 453826 E, 5504184 N); Golden Sceptre (UTM Zone 16: 453412E, 5504088N); and Throne (UTM Zone 16: 453053E, 5504168N)) were uncovered by prospecting, stripping, trenching and sampling. Cross-cutting shear zones appear to control gold mineralization. Mapping by Kodiak Exploration on the Solomon’s Pillars property indicated the presence of a 10 m wide shear zone that overprints both the banded iron formation and clastic metasedimentary rocks. The shear zone consists of related quartz-carbonate veining and sulphidized banded iron formation (Roach 2008). The quartz-carbonate-rich shear zones cross-cut the west-trending clastic metasedimentary–banded iron formation sequence at a high angle, ranging from 230° to 240°. The shear zones are most prominent at the Royal Crown and Throne occurrences and range from 2 to 7 m wide along the southern portions of the stripped areas. Mineralization within the zones most commonly consists of pyrite and arsenopyrite, with minor chalcopyrite. Sulphide content varies from 10% to 25% in the most intensely sheared portions (in particular, the western end of the Throne occurrence), which contain small (0.5 to 2 cm) lenses of massive pyrite and disseminated fine-grained needles of arsenopyrite. The zones are extremely gossanous and in places exhibit prominent chlorite-sericite alteration. Quartz-carbonate veining within the shear zones is parallel, en echelon and boudinaged, averaging 2 to 3 cm wide, and ranging up to 70 cm in width. Visible gold was noted within the quartz veins at locations along the western end of the Throne occurrence and at the Golden Scepter showing. Sampling by Sage Gold and staff of the Thunder Bay North Resident Geologist office, returned channel sample assay results as high as 351.58 g/t Au over 1.28 m (Royal Crown occurrence) and grab samples assaying up to 154.09 g/t Au (Sage Gold Inc., news release, September 8, 2009). Sample results from a 26-hole, 3777.5 m diamond-drilling program returned assay values up 5.75 g/t Au over 5.19 m (ibid, November 12, 2009).

Jun 08, 2023 (Therese Pettigrew) - Mineralization at the Throne showing is described as approximately 070 to 080 trending silica-sericite-chlorite-ankerite-pyrite-arsenopyrite altered and sheared fine-grained sediments with associated quartz veining and stockworking. The shear zones can be several metres wide and traced along strike for hundreds of metres to kilometres. The main shear occurs just south of the primary iron formation unit on the property; however, these shears can also be found north of the iron formation. Sulphide and gold values vary considerably along the shear zone's strike and width. Gold values are strongly associated with high sulphide contents, particularly arsenopyrite. Grab samples from the Throne occurrence returned up to 19.139 g/t Au. Channel samples from the Throne showing returned 2.8-13.47 g/t Au (Assessment report 20000013690).
