Capsule Geology

The Arnie Flats occurrence is located on a west striking ridge, approximately 2 kilometres west of Golden Hope Peak and at an elevation of 2100 metres.

The area is underlain by highly deformed Triassic and older (?) volcanic and sedimentary rocks of and younger aplite and feldspar porphyry dikes, and granitic intrusions. The volcanic rocks are the oldest units and are tentatively assigned to the Slocan or Kaslo Group, while the younger sedimentary rocks are correlated with the Slocan Group. A complete regional geology summary can be found in the Heino-Money (MINFILE 082FNW234) occurrence.

Locally, tuffaceous and meta-basaltic andesites near a hybrid diorite sill host two sub-parallel calc-silicate skarn zones. Sulphide mineralization consists of disseminated and stringer pyrite with pyrrhotite and trace argentite or tetrahedrite. Alteration minerals include epidote, quartz and chlorite. The zones trend east- northeast with a moderate dip to the southwest and have been traced for 120 metres along strike.

In 1984, trench samples yielded values up to 260.5 grams per tonne silver and 0.69 gram per tonne gold (Assessment Report 26847).

In 1989, diamond drilling yielded from 0.10 to 0.79 gram per tonne gold with 42.7 to 178.1 grams per tonne silver over lengths of 0.91 and 2.74 metres, respectively (Assessment Report 26847).

The area has been explored historically in conjunction with the nearby approximately Heino-Money (MINFILE 082FNW234) occurrence to the northwest. In 1979 and 1980, the area was prospected by Arnold and Elaine Gustafson. Later in 1980, after the discovery of high- grade gold values on the nearby Tillicum Mountain (MINFILE 082FNW234) property, the area was subsequently acquired by the Esperanza Explorations Ltd and Welcome North Mines Ltd. joint venture, which led to additional claim staking (Til 1-4 claims) to include the Silver Queen (MINFILE 082FNW220) ground to the south. Welcome North terminated the joint venture in March 1982. In June 1982 La Teko Resources optioned a 50.4 per cent interest in Esperanza Explorations. Work in 1981 and 1982, included geological mapping, prospecting, geochemical sampling and an airborne geophysical survey. In 1984, a program of rock sampling and geological mapping was completed. The area was explored in conjunction with the Tillicum Mountain occurrence by Esperanza Explorations through 1989. This work included five5 diamond drill holes over a strike length of approximately 1000 metres. In 1997, AMT Resources and IBEX Resources completed a program of geochemical sampling, trenching and a ground electromagnetic survey on the area. In 2001 and 2002, 1330275 Ontario Limited completed programs of rock, silt and soil sampling and geological mapping on the area. During 2008 through 2014, AMT Industries Canada completed programs of soil sampling, a ground electromagnetic survey and remote sensing analysis on the area. In 2020, MGX Minerals Inc. optioned the Heino Gold property.
