Treasure Mountain

The Terrace project owned by Decade Resources Ltd stretches from 10 to 40 air kilometers east of Terrace, B.C., on the northern slopes of Copper (Zymoetz) River valley. The project consists of 51 contiguous minerals claims totaling 22,900 hectares formed by the Treasure Mountain, Dardanelle, Nobody Knows, Kleanza and Terrace Gold (Excelsior) claims. The property is underlain by a complex boundary zone between two prominent tectonic assemblages: the volcanic island-arc assemblage of the Stikinia Terrane in the east and the intrusive rocks of the Coast Plutonic Complex (Cretaceous-Tertiary?) to the west.

The Treasure Mountain property consists of 29 mineral claims with a total area of 11,137.21 hectares.

On the Treasure Mountain Trend approximately 22 copper-silver showings occur over a 15 km belt. On the Treasure Mountain area, copper-silver mineralization is hosted mostly within vesicular and to lesser extent massive basalt. Mineralization is dominated by bornite, chalcocite and malachite with lesser covellite and chalcopyrite and little to no pyrite. These sulphides constitute from trace to 5% of the rock forming grains, small blebs and veinlets which show strong association with silicification and or quartz-epidote veins. This type of mineralization does not contain any appreciable gold but is enriched in silver fitting the model of a red bed type copper-silver mineralized system. There does appear to be any association with faults or fracture zones.

For Treasure Mountain, exploration has identified 3 periods of mineralization: namely copper-silver bearing sulphides in volcanic red beds followed by copper sulphide-silver bearing shear zones and last, a late-stage epithermal copper sulphide-silver-gold bearing quartz – carbonate stockworks. Copper bearing sulphides include chalcopyrite, bornite and chalcocite and possibly native copper.

The section on the most prominent showing is extracted from a 43-report on the Copper River project by Mastalerz and Walus in 2020. The section is as follows:

Treasure Mountain Property

The most important mineralization type of this property occurs mainly within Purdex and DF zones which contain copper-silver mineralization hosted mostly within vesicular and to lesser extent massive basalt. This type of mineralization is dominated by bornite, chalcocite and malachite with lesser covellite and chalcopyrite. They constitute from trace to 5% of the rock forming grains, small blebs and veinlets which show strong association with silicification but no obvious association with faults or fracture zones. This mineralization type bears certain characteristics of the Volcanic Redbed (D03) mineralization as defined by Lefubure, D. V. and Church, B.N. (1996) in the British Columbia Mineral Deposit Profiles. However, strong association with silicification contradicts this conclusion indicating formation in hydrothermal environment.

Considerable work has been done on the zone which include trenching, drilling and construction of an adit. This is the main copper-silver zone within the Treasure Mountain property. MINFILE gives the following description of the zone: “A 26 metre surface chip sample assayed 2.44 per cent copper and 0.4 grams per tonne silver (Minister of Mines Annual Report 1965). A parallel zone, similar in character and 60 metres to the west, measures 30 by 10 metres. Surface samples average 3.26 per cent copper.” The Company verified these results during the 2017 exploration program where a total of nine chip samples ranging in length from 0.9 to 4.0 metres were collected. All samples except one were collected from old trenches. They assayed from 0.49 to 5.51 % copper and from 7.2 to 42.7 g/t silver.

A total 4 holes totaling 810.37 m were completed to test the Odra zone on Treasure Mountain utilizing a helicopter supported drill in the 2023 field program. Overall core sample results indicated from <0.001 to 0.66 g/t Au, <0.01 to 6.72 g/t Ag, 1 ppm to 2.40 % Cu, 0.6 to 11.5 ppm Pb and 23 to 171 ppm Zn. The best intersection was 1.83 m of 0.326 g/t Au, 3.01 g/t Ag and 0.463 % Cu from 107.32 to 109.15 m in DDH-TM-23-2. The table below shows the significant assay results >0.1 % copper as follows:

Work indicated a zone that was 50 x 30 m with numerous copper bearing veins and shears in the NE part of the North Ridge area on the project area. Results for this area are shown in the table below showing the results for 59 float, select grab, and chip samples.
