Mineralization in the Simpson mine occurs as a quartz filled shear zone which hosts pyrrhotite, pyrite and chalcopyrite across a width of approximately 30 meters. Mineralization occurs in an ultramafic dike in the adit. The dike intrudes metasediments and greenstone. The area is underlain by rock of the Devonian to Permian Knob Hill Group consisting of quartzite, chert, siliceous argillite and siliciclastic rocks.
Some of the work was common to both the Lucky John (082ESE072) and Simpson mine (082ESE179) area and the same work history is included for both.
The earliest records of work in the area date back to 1901. The property in the area of the Lucky John was then known as the Exchange. Over the years a number of open cuts and pits were dug to expose gold-bearing massive sulphides.
In 1939, 330 tonnes of ore were shipped to the Trail smelter from the Simpson (Zucco) mine which yielded 8055.8 grams (259 ounces) of gold and 2799.3 grams (90 ounces) of silver (Minister of Mines Annual Report 1939, page 91). The ore grade was 24.34 grams per tonne gold and 8.57 grams per tonne silver. A total of 213 metres (700 feet) of drifting and cross-cutting were driven in an attempt to extend this zone but without success.
From 1966 to 1969, Byrell Minerals and Fento Mines conducted a work consisting of I.P., diamond drilling (6 holes) and stripping on the Glover zone.
From 1975 to 1976, geological mapping, magnetometer surveys and 601 metres of diamond drilling (CB-75-l to 11) was completed by Consolidated Boundary Exploration Ltd.
In, 1980 the property was optioned by Aries Resources Inc. and mapping, magnetometer and VLF-EM surveys were conducted. In 1983, soil geochemical and magnetometer surveys as well as a geological mapping and trenching program were completed by Grand Forks Mines. In 1984, 130 metres of diamond drilling (CBG-84-1 and 2) was completed on the Main and Eastern zones of the Hek property by Consolidated Boundary Exploration Ltd. In 1986, Consolidated Boundary Exploration Ltd. completed a program of 9 diamond drill holes (783 metres) on and around the Glover Creek zone. In 1987, Noranda operated the property, most of which was owned by Consolidated Boundary Exploration Ltd. They conducted mapping and collected 753 soil and 57 rock samples.
In 1995, 18 kilometers of grid were established over part of the area by John Kemp and a magnetometer survey, sampling and prospecting survey completed.
A 1998 localized geological mapping and sampling program was completed over the Main Zone by Carnival Resources Ltd. and resulted in the delineation of a 121 metre long and more than three metre wide mineral zone. A 1999 localized geological mapping and sampling program over the Glover Creek adit zone disclosed low gold values within a massive sulfide skarn zone. A 1999 localized geochemical program north of the Glover Creek adit zone disclosed gold in soil values of up to 154 ppb gold. This zone was designated as the Glover Creek anomaly. In 2000, Carnival Resources Ltd. collected 9 soil samples on the Glover Creek anomaly.
In 2004, Ingenium Capital BC Ltd. conducted minor geological mapping and sampling on the Main, Eastern and Glover Creek zone.
