The 1250N occurrence is located on northeast-facing slopes to the north of Tillicum Mountain at an elevation of approximately 1900 metres. The Tillicum Mountain (Heino-Money, MINFILE 082FNW234) gold occurrence is located approximately 650 metres to the south.

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, a parallel series of conformable sulphide-rich bands, up to 0.3 metre wide, are hosted by a sequence of rusty schistose and siliceous rocks. Sulphide mineralization consists of pyrrhotite with up to 10 per cent sphalerite.

In 1982, a chip sample assayed 8.9 grams per tonne gold and 35.2 grams per tonne silver over 2.6 metres (Assessment Report 11161).

The area has been explored historically in conjunction with the nearby 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. 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.
