GPEX’s “Treasure Mountain Suite” consists of three properties, the “Morning Star,” the “Argentum” and the “High Silver” claims. These tenures are closely located to one another and jointly comprise 294.156 hectares. The claims are situate on Treasure Mountain in the upper Tulameen River region of British Columbia. The area represents one of the older hardrock mining camps in the southern west-central sector of the province. Exploration and development on the mountain commenced in 1894. Located 27 kilometers east/northeast of Hope, the area is readily accessible by 38 kilometers of well maintained logging roads departing from the Coquihalla Highway, 1.5 kilometers north of the toll booth (52 kilometers north of Hope), followed by approximately three kilometers of dirt road. These claims are conducive to prospecting for approximately seven months out of the year.
The general underlying geology is comprised of tuffaceous and politic sediments of the Upper Jurassic Dewdney Creek Group. Mineralization is generally consistent in character throughout the area. It consists of silver-bearing sulfides in quartz carbonate veins localized along locally prominent, steeply dipping fault structures, subsidiary faults and tension fractures. Veins vary in width and usually consist of a central core of massive sulfides with veinlets and disseminations distributed outward.
The immediate area, known as the "Treasure Mountain" or "Summit" property, has seen sporadic but at times, intensive activity during four periods following its discovery in 1894. Initial work was carried out from shortly after the discovery to about 1913. From 1920 to 1932 some production was realized and then in the 1950's the Treasure Mountain area again produced a minor amount from a 50 ton per day mill. During this decade Huldra Silver Inc. hadbeen actively exploring the claims immediately east of the current “High Silver” tenure. The Summit claim, a portion of the former Summit Camp, is favorably situated just west of Huldra Silver and has shown the existence of similar mineralized veins.
By 1900, high grade assays from varied properties included 0.08 oz/ton gold, 23.8 oz/ton silver and 3.6% lead. Galena mineralized payshoots assayed up to 130 oz/ton silver and 200 oz./ton silver. The “old” Morning Star claim, which comprises 1/12 the ground as that of the current Morning Star tenure, had similar but more minor showings. A summary of the metals shipped to the end of 1952 from two neighboring properties indicates the deposits produced 40,431 ounces of silver, 392,357 pounds of lead and 102,079 pounds of zinc from an estimated 1,300 tons of concentrates. In 1954 a 50 ton concentrator was installed. In 1987, Harrisburg-Dayton conducted magnetometer and soil geochemistry surveys over neighboring areas. Trenching was carried out in late October and exposed intermittent vein segments along a 170 meter strike trend that yielded silver values of 88.38 oz/ton and 50.9 oz/ton over 0.5 and 0.9 meters respectively.
Activity in the region, as with that throughout the mining industry, has fluctuated according to the rising and falling precious metals markets. Following decades of low prices, the upswing in precious metals has generated renewed interest and extensive explorations. Firms and individuals are now focused on many of the older claim areas. With the opening of GPEX’s mineral property portfolio, these and several other dynamic prospects of high potential, are now made available to parties bearing serious hardrock interest. Whether a larger mining interest, a junior firm desiring to expand upon its operations or holdings, the entrepreneurial mining speculator, the individual seeking investment opportunities, the small operator desiring a Mom & Pop operation, or, the junior prospector seeking a quality property to engage in hardrock explorations, quite possibly the acquisition of one or more of GPEX’s properties will satisfy the search.

Capsule Geology The Treasure Mountain region is underlain by northwest striking, moderate to steeply southwest dipping volcanic and sedimentary rocks of the Lower-Middle Jurassic Dewdney Creek Formation (Ladner Group) and Lower-Upper Cretaceous Pasayten Group, intruded by numerous dikes and sills. The Dewdney Creek Formation comprises volcanic rocks and a minor amount of sediments and consists of tuff, breccia and agglomerate with interbedded argillite and conglomerate. The Dewdney Creek Formation is considerably altered; pyrite is commonly present and many outcrops are rusty. The Pasayten Group includes predominantly arkose, argillite and conglomerate. Locally, the two sequences are separated by a northwest striking, northeast dipping fault, but in large part are conformable.
Mineral occurrences in the area are hosted in the Treasure Mountain fault and in and near subsidiary faults, and comprise one or more quartz-carbonate veins or stringers that branch and split and vary considerably in width and attitude (see Treasure Mountain, 092HSW016).
The Morning Star occurrence is underlain by northwest striking, southwest dipping Dewdney Creek Formation andesite and tuffaceous rock. A fracture zone hosts an oxidized quartz-calcite stringer vein zone that varies from a few centimetres to 45 centimetres in width. The zone strikes 075 degrees and dips 45 degrees south and is mineralized with galena, sphalerite and pyrite with manganese oxide staining. A second stringer vein zone outcrops 22 metres southwest of the first and strikes 045 degrees with 80 degree south dips. This zone is 60 centimetres wide and is sparsely mineralized.
Underground development along the fracture zone revealed that it is very narrow and sparsely mineralized with the exception of a 3-metre section where the zone is 60 centimetres wide and mineralized with galena, sphalerite, tetrahedrite and pyrite in a gangue of gouge and silicified and brecciated andesite wallrock. Crosscutting intersected another zone (apparently a widened continuation of the first) 7.6 metres wide containing three mineralized fractures, each 60 centimetres wide, separated by bands of altered andesite. The fractures contain sphalerite, galena and pyrite in a gangue of brecciated wallrock.
A grab sample of ore in an opencut above the adit portal assayed 1.37 grams per tonne gold, 2571 grams per tonne silver, 42 per cent lead and 8 per cent zinc (Minister of Mines Annual Report 1927, page C255).

The Treasure Mountain region is underlain by northwest striking, moderate to steeply southwest dipping volcanic and sedimentary rocks of the Lower-Middle Jurassic Dewdney Creek Formation (Ladner Group) and Lower-Upper Cretaceous Pasayten Group, intruded by numerous dikes and sills. The Dewdney Creek Formation comprises volcanic rocks and a minor amount of sediments and consists of tuff, breccia and agglomerate with interbedded argillite and conglomerate. The Dewdney Creek Formation is considerably altered; pyrite is commonly present and many outcrops are rusty. The Pasayten Group includes predominantly arkose, argillite and conglomerate. Locally, the two sequences are separated by a northwest striking, northeast dipping fault, but in large part are conformable. Several faults occur. Two faults cross the southwest part of the region and strike east and dip steeply south, but one splay of one fault dips north.
A shaft explores the fault, where a 38 centimetre quartz vein stringer zone contains abundant galena and sphalerite with variable amounts of pyrite, pyrrhotite, arsenopyrite and chalcopyrite. Petrographic studies revealed proustite and tennantite as inclusions in pyrrhotite. Wallrock and gouge constitute a major portion of the fault zone. Sericite and epidote occur as disseminations in the quartz veins and along vein selvages. Quartz crystals are common. An opencut along the fault exposed a number of very narrow stringers of galena across a width of 1.8 metres of sparsely mineralized rock. Limonite (mainly goethite) occurs in fractures cutting the veins and sulphide mineralization. To the west, the zone can be traced for 152 metres but consists of gouge and bleached wallrock. Ninety-one metres east of the shaft, widely separated quartz stringers form a zone 0.9 metre wide. Recent trenching of the fault structure starts 74 metres west of the shaft and extends east for a total distance of 315 metres. Channel sampling from the trenches across 1.37 metres of vein yielded a best assay of 0.19 per cent copper, 4.51 per cent lead, 5.87 per cent zinc, 396.61 grams per tonne silver and 2.70 grams per tonne gold (Assessment Report 18111). Grab samples at the Summit shaft yielded up to 0.5 per cent antimony (Dewonck, 1987). Minor production took place in 1951.
