The Izzi occurrence is located near a ridge top 6.5 kilometres north of the west end of Tutizzi Lake, approximately 90 kilometres northwest of the community of Germansen Landing.

The hostrock is a hornblende-bearing pyroxenite of the Upper Triassic to Lower Jurassic Aiken Lake Intrusive Complex, which is possibly related to the Lower Jurassic to Lower Cretaceous Hogem Plutonic Suite. The ultramafic rocks contain variable amounts of olivine and plagioclase phenocrysts and are interbanded with, and gradational into gabbroic and monzonitic phases (Assessment Report 14809, Geology map). Andesitic volcanic rocks of the Upper Triassic Takla Group outcrop east of the occurrence.

Locally, at surface gossan zones are developed in decomposed rocks above timberline in the area of the occurrences and chalcopyrite, malachite, hematite, and pyrite have been identified. Drilling on the occurrence area has intercepted a pyroxene porphyritic volcanics with calcite±quartz±pyrite±magnetite±chalcopyrite veins.

In 1985, rock chip samples yielded results as high as 2.8 grams per tonne gold (sample IZ2943, Assessment Report 14809).

In 1991, a rock sample (NR03) of fine-grained ash tuff hosting quartz veinlets with pyrite assayed 0.34 per cent copper (Assessment Report 22121).

In 1992, a chip sample (12025) of andesite porphyry with pyrite blebs and malachite-azurite staining assayed 1.20 per cent copper and 1.10 grams per tonne gold over 2.0 metres (Assessment Report 22860).

In 1994, diamond drilling on the area yielded intercepts including 0.48 per cent copper and 3.95 grams per tonne gold over 0.4 metre at a depth of 53.0 metres from a pyroxene porphyritic volcanic with zones of calcite-sulphide veining in drillhole 94DH003, located several hundred metres east of the occurrence; 0.26 gram per tonne gold over 16.0 metres of pyroxene porphyritic volcanics with calcite-quartz-pyrite-magnetite veins and trace chalcopyrite in hole 094DH004, located several hundred metres south of the occurrence and 0.87 per cent copper and 1.14 grams per tonne gold from a 0.10-metre wide pyrite-chalcopyrite vein in hole 94DH005, located several hundred metres north of the occurrence (Assessment Report 23780).

In 1998, three rock samples (RR-01, -42 and -50) from the occurrence area yielded 3.47 to 8.72 grams per tonne gold, with up to 0.28 per cent copper (Assessment Report 25856).

In 2004, two chip samples (32004 and 32005) of altered andesite with quartz-carbonate veinlets from the occurrence area yielded 1.01 and 1.19 grams per tonne gold over 6.0 and 1.5 metres, respectively (Assessment Report 27730).

In 2005, two samples (65728 and 65738) of fractured and mineralized augite porphyry assayed 1.3 and 14.9 per cent copper with 0.17 and 2.38 grams per tonne gold, respectively (Assessment Report 27972).

In 2018, a rock sample (SW18-038) if iron carbonate–altered andesite with quartz-pyrite veins and crosscutting chlorite-quartz-potassium feldspar-magnetite veins from the occurrence area assayed 2.35 grams per tonne gold (Assessment Report 38375).

Work History

During the 1970s, the Abe claim area was explored by the UMEX-Wenner Gren Joint Venture. The property was covered by a regional airborne magnetic survey, and soil and stream sampling surveys. Four magnetic anomalies were defined: three on the margin of a diorite stock and one in Takla Group volcanics near a contact with the Hogem Batholith. Soil sampling outlined a 550- by 1550-metre molybdenum anomaly on the Abe 7 and 8 claims. Copper-molybdenum silt anomalies were discovered on three of the streams that drain the property. No samples were analyzed for gold.

In 1981, Mattagami Lake Exploration Limited carried out geochemical sampling and geological mapping on the then Alta-1 and 2, and Brit-1 and 2 claims. In 1985, Golden Rule Resources Ltd. collected soil, silt, and rock samples. In 1985, Suncor Inc. completed a program of rock, silt and soil sampling on the area as the Izzi claim.

During 1991 through 1994, Swannell Minerals Corp. completed programs of prospecting, geological mapping, geochemical (rock, silt and soil) sampling, a 13.1 line-kilometre ground magnetic survey, a 22.5 line-kilometre induced polarization survey and 10 diamond drillholes, totalling 897.9 metres, the area as the Abe 1-8 claims.

In 1998, Starfield Resources Inc. completed an extensive program of geological mapping, geochemical (rocks, silt and soil) sampling, a 35.8 line-kilometre ground magnetic and a 27.2 line-kilometre induced polarization survey on the Abe 1-8 and Norm 1-4 claims.

In 2004 and 2005, Commander Resources Ltd. completed programs of prospecting and geochemical (rock and soil) sampling on the Abe property. In 2007, Geoinformatics Exploration Canada Ltd. conducted a program of geological mapping, minor geochemical (rock and silt) sampling and five diamond drill holes, totalling 1600.0 metres, on the area as part of the regionally extensive Mesilinka property, which included the Abe property.

In 2012, on behalf of Commander Resources Ltd., a field program comprising reconnaissance prospecting, mapping and geochemical sampling was carried out on the Abe property. A total of 328 soil samples, 22 rock samples and 8 silt samples were collected and submitted for analysis.

During 2018 through 2021, Commander Resources Ltd. completed further programs of geological mapping and geochemical (rock and soil) sampling on the Omineca (Abe) property.
