Capsule Geology

The Ant (Opus) occurrence is located southwest of McLeod Lake and approximately 15.5 kilometres east of the north end of Carp Lake.

The area is underlain by the Upper Triassic Takla Group near its eastern contact with the Cretaceous Wolverine Range Plutonic Suite and paragneiss metamorphic rocks of the Upper Cretaceous to Eocene Wolverine Metamorphic Complex. The contact between these two groups is a fault.

In the area of the showing the dominant rock type is basaltic andesite that has been intruded by north- to northeast-striking, vertically dipping diorite dikes 1.5 to 30 metres wide. Mineralization consists of chalcopyrite and pyrite within quartz veinlets hosted by both the basaltic andesite and diorite.

In 2020, a sample from a quartz vein cutting diorite assayed 0.95 gram per tonne gold (Assessment Report 39660).

Work History

In 1971, magnetometer and soil geochemistry surveys and 30 metres of hand trenching were completed on the Ant claims by AMAX Exploration Inc. A year later, 60 metres of bulldozer trenching was performed.

The 80-unit Opus 1-4 claim group staked by Cominco Ltd in 1987 was acquired to cover coincident magnetic and geochemical anomalies. Preliminary silt sampling in 1987 revealed two gold anomalies on the property. In 1988, Cominco conducted a geochemical and prospecting program collecting a total of 60 silts, 47 soils, 12 pan concentrates and 20 rock samples. The Opus 4 covers the Ant area, where Cominco conducted some sampling and mapping as part of the program.

In 1992, Placer Dome Inc. completed a 44.5 line-kilometre airborne magnetic and electromagnetic survey on the area immediately west of the occurrence as the Hamm 1-2 claims.

The area was restaked in 2006 (as the Ant claim) to cover a copper prospect originally discovered by Amax Exploration Inc in 1970. A preliminary sampling grid was established at that time to follow up pyritic outcrops of altered and mineralized Takla rocks discovered during a reconnaissance of the region. In 2006, 13 soil samples were collected along road 9283 at the west claim boundary. These samples and a compilation of prior work suggests the presence of a weak copper and zinc anomaly in the west part of the Ant 1 claim.

In 2010, Triple Dragon Resources Inc. prospected and sampled the Ant property.

In 2020 and 2021, Golden Planet Mining Corp. completed a regionally extensive program of prospecting, geological mapping, geochemical (rock, till and soil) sampling and a 4851.0-line-kilometre airborne magnetic and electromagnetic survey on the area as the Rider property.
