The Terrace Properties are composed of three main claim blocks; namely Terrace Gold-Dardanelle-Treasure Mountain group of claims located about 10 to 35 air kilometers east of Terrace, B.C., on the side of the Zymoetz (Copper) River valley . The property consists of 48 contiguous mineral claims owned by Decade Resources Ltd. of Stewart, B.C. Within the boundaries of the property occur numerous mineral showings listed on the BC MINFILE. The Terrace Gold also includes one additional mineral claim – 505585 – which is under option to Decade.
The Terrace area properties include 4 separate claim holdings that have a variety of different types of mineralization. Included in the different types are the following:
- Red bed copper-silver mineralization in Hazelton group volcanic rocks.
- Felsic dykes with quartz sulphide veins on the boundaries hosting gold bearing mineralization.
- Quartz-sulphide veins with significant gold-silver mineralization.
- Shear hosted gold-silver mineralization associated with copper mineralization.
- Porphyry style copper-gold and copper-molybdenum-gold mineralization in granitic to dioritic rocks which have invaded volcanic rocks of the Hazelton Group Lower to Middle Jurassic.
The Terrace Gold property is underlain by predominant intrusive rocks which belong to the Coast Plutonic Complex and/or Kleanza Plutonic Suite. The granodiorite-diorite intrusive rocks are generally bound to the east by the andesite volcanogenic rocks of the Triassic/Jurassic Telkwa/Hazelton Group. Few irregular slivers of the roof pendant of the intrusion complex consist of older Paleozoic sedimentary and volcanogenic rocks.
On the Gem property, located within the larger Terrace Gold property, the main showing is reported as a quartz-pyrite vein with minor chalcopyrite. Reports indicate that the vein ranges from 15 to 50 centimetres in width, and is exposed intermittently along the strike length for 300 metres and about 120 metres downdip. Two adits explore the mineralization with reports of 108.27 g/t Au and 195.93 g/t Ag over 0.23 m near the face and 104.74 g/t Au and 180 g/t Ag over 0.4m at the face of the northern portion of the lower adit. It appears that the zone is becoming wider as the zone is traced north. Historic surface grab sampling several hundred meters north of the adits returned over 154 g/t Au.
Reserves of about 4355 tonnes averaging 26.06 grams per tonne gold and 59.31 grams per tonne silver were calculated over a length of 34 metres and a width of 0.4 metres for the underground explored portion of the Gem vein as reported in BC Minfile.
The above results on the Gem prospect have not been confirmed by Company assaying and are used for reference purposes only.
On the Dardanelle claim area, a 5.5 to 7.3 metre wide quartz-albite dyke trending 075 degrees and dipping 75 degrees north occurs in granodiorite of the Cretaceous to Tertiary Coast Plutonic Complex. Quartz veins, 0.3 to 2 metres wide, occur intermittently along both contacts of the dyke for 700 metres and a vertical depth of 180 metres. Minerals observed in the quartz veins include pyrite, sphalerite, chalcopyrite, argentite, galena, arsenopyrite, bornite, covellite and gold.
A 1.2 metre sample from the bottom of a shaft assayed 9.3 grams per tonne gold, 61.7 grams per tonne silver, and 1.8 per cent copper (Minister of Mines Annual Report 1918). A 0.4 metre adit sample assayed 13.0 grams per tonne gold and 361.4 grams per tonne silver (Geological Survey of Canada Memoir 205). A 25.4 kilogram sample of ore sent for testing assayed 27.9 grams per tonne gold, 624.7 grams per tonne silver, 0.64 per cent copper, 8.16 per cent lead and 3.15 per cent zinc (Geological Survey of Canada Memoir 329).
In August 1983, a report by S. Reamsbottom suggested that the property contains reserves of approximately 181,440 tonnes grading about 7.5 grams per tonne gold and 17.1 grams per tonne silver (George Cross Newsletter Nov.13, 1984).
In 2005, drilling intersected 1.37 m of 4.5 g/t Au in one drill hole while a deeper hole intersected 1.22 m of 12.85 g/t Au.
The above results on the Dardanelle prospect have not been confirmed by Company assaying and are used for reference purposes only.
The Treasure Mountain claims have a great potential to host copper-silver and /or copper-gold deposits. It features numerous copper showings as well as newly located copper-gold showings of which only part have been examined recently.
Exploration on the Treasure Mountain property is limited by two major factors. The property is covered by lush vegetation and feature few outcrops. The outcrops are strongly leached of copper which makes copper mineralization very difficult to detect by prospecting or soil sampling. Outcrops are often so strongly leached that there is no sign of high grade copper mineralization on the surface which can only be found after removing the first 10-15 cm of barren rock. Highlights of 2017 sampling include:
- 7 g/t Au, 1.14% Cu and 35.8 g/t Ag from a new showing that is a partially exposed shear in an overburden covered area.
- 98 g/t Au and 1.51% Cu from a grab sample from an old trench.
- A weighted average of 3.37% copper and 30.68 g/t silver from nine chip samples.
Sample results from some of the tested zones are described below:
During the 2017 exploration program 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. They gave a weighted average of 3.37% copper and 30.68 g/t silver.
The 2017 program consisted of resampling of the 2007 pits and trenches. A composite grab collected from a 15-20 cm wide, partially exposed fault assayed 4.01% Cu, 55.5 ppm Ag and 61 ppb Au. Grab sampling of a 10-20 cm wide quartz-chalcocite vein yielded 4.43 % Cu, 45 ppm Ag and 38 ppb Au.
During the 2017 program three old trenches were found and resampled in the area designated as the Trail zone in a 2008 Assessment Report. Sample A17-68, a grab from one of the trenches returned 1.51% Cu and 9.98 g/t Au. The sample represent quartz-carbonate replacement of feldspar porphyritic andesite or basalt with 2-3% disseminated bornite and chalcopyrite.
The zone, partially exposed by an excavator during a previous exploration program has quartz-carbonate veins with minor pyrite and some malachite stain. Grab sampling of a vein returned 1.14% Cu, 35.8 g/t Ag and 22.7 g/t Au.
