Tagish-025 (Gold-Silver) B.C. -
Property Description
The Tagish-025 gold-silver property is located 25 km west form the town of Atlin, BC. History in the area dates back to the early 1900’s when the White Pass engineers made there way to the placer gold fields of Dawson Yukon and Atlin, BC.
The Tagish-025 property has similarities to the world class Bendigo gold
district of Australia which produced 18 million ounces of gold and the
tremendous 170 million ounce gold resource of the Muruntau deposit in
Uzbekistan.
Geologist Gary R. Thompson discovered gold-silver mineralization off the east shore of Tagish Lake in 1988. Since discovery nearly 3km of strike has been mapped to date through, soil-rock geochemical surveys, geological mapping and trenching.
The property is bounded to the west by the long-lived deep-seated Llewellyn Fault system and the Coast Crystalline Complex. The claims cover a 6 km long, 10- 100 m wide, 025 ° trending splay fault off the Llewellyn Fault system. The property is dominated by Jurassic Laberge group argillite, graywacke, siltstone, limestone and conglomerate (Turbidite), which are underlain by Triassic Stuhini group volcanics and carbonate. This pile has under gone lateral shortening by some 45 percent. Many cross faults, folds and several high level granodiorite to porphyritic intrusive phases complicate the geology. Phyllic, illite, silica and carbonate are the main alteration assemblages associated with epithermal-mesothermal quartz flooding stockwork-microstockwork and breccia. Gold and silver mineralization occurs in the hanging and footwall as native metal and associated with disseminations, blebs and fracture fillings of arsenopyrite, pyrite. Gold and silver is hosted in quartz breccia and stockwork and turbidite sediments.
The Main Zone strikes for 360m, widths vary up to 15m. Seventy-two rock samples returned an average of 3 g/t Gold and 57 g/t Silver. Grades to date range up to 8.7 g/t Gold, 1374 g/t Silver and a gold equivalent of 0.88 oz/t . An arsenic soil anomaly is centered within the southern portion of the main zone. A Grab sample returned 5.5 g/t Gold and 495 g/t Silver.
Hand Trench 96TR03 sampled the hanging wall sediments returning 4 g/t Gold and is open in the west direction. Several drill targets have been identified. (See Compilation Map 2004 Main Zone, Auto-CAD drawing). A cyanide bottle roll test was conducted on rock samples from the Main zone. The bottle roll test returned 75% gold in 24 hours.
A 2000 m drill program is proposed for the Tagish-025 Project in 2005.
Hand trenching results are as follows:
The Bear-ox Zone displays a 700m x up to 100m arsenic+-gold soil anomaly. Soils from 2003 returned 10450, 8900, 5100, 4530, 4605 and four samples near 2700 ppb gold. Past soil results range up to 18,760 ppb Gold. Grid line 5225N returned 10m > 1000 ppb Gold and including 3m of > 10,000 ppb Gold and 7m of 5455 ppb Gold from 1m soil sample stations.
Hand trenching results are as follows:
Weak S.P. geophysical anomalies correspond with some of these geochemical results and several moderated S.P anomalies were identified outside the fault zone. XRD analysis has identified Samarium Telluride from pyritic-clay associated with anomalous gold. Drill targets have been identified.
The Barny Zone displays anomalous Gold, Silver, and Sb values for a strike of > 1 km. Breccia and stockwork qtz-carbonate zones are associated with high-level granodiorite porphyry, cross faults and overturned folds. A rock grab sample returned 1 g/t Gold.
The Central Zone displays anomalous gold from soils and is the widest portion of the structure.
