Vancouver — Bright Star Ventures (BSV-V) has outlined this year’s exploration targets on its 49-sq.-km Tulameen platinum project in the Cascade mountains of southwest British Columbia, about 26 km northwest of Princeton.
The company is particularly interested in the 5.6-sq.-km Grasshopper Mountain prospect where two previous operators have recorded strong platinum values in dunite intrusive rocks. Bright Star will target the area for "intensive exploration" to test new theories about the origin of placer platinum nuggets found in the Tulameen river and streams that drain Grasshopper Mountain. The Tulameen watershed was responsible for a recorded 20,000 oz. of placer platinum.
The Grasshopper claims are cover southwest flank of Grasshopper Mountain. The claims are underlain by dunite and peridotite of the Early Jurassic-aged Tulameen Ultramafic Complex. It is classified as a zoned Alaskan-type intrusive complex. The dunite-rich core of the complex extends south-southeast from Grasshopper Mountain for 5 km to Olivine Mountain claim group and is fringed by zones of clinopyroxenite and gabbro.
To date, five large out-crops have been discovered that have returned hosted platinum group metal (PGM) mineralization. Channel samples across a platinum-bearing chromite zone returned 7.8 grams platinum and 20.0% chromium over 3 metres and 15.0 grams platinum and 5.6% chromium over 2 metres. In 1986, Newmont Exploration Canada drilled a chromiferous dunite measuring 800-by-300 metres. Significant intercepts returned 4.70 grams platinum over 5.57 metres and 5.58 grams platinum over 1.64 metres.
Bright Star has the right to earn a 100% interest on the Grasshopper claims by paying $40,000 in cash and $200,000 in exploration expenditures over the next two years. In addition the junior must issue issuing 300,000 common shares and maintain annual property payments. The property is subject to a 2% net smelter royalty.
A second target for this season’s exploration has been chosen in the gabbro rocks situated southeast of Olivine Mountain. This area is host to strong magnetic-resistivity anomalies that were outlined last year during an airborne geophysical survey.
A portion of the company’s wholly-owned BJP-1 claim-block which hosts the magnetic-resistivity anomalies, has been subjected to a soil-sampling geochemistry program. Results indicated copper-palladium-platinum-gold anomaly covering a 400 by 600 metre grid. The multi-element assay results returned values up to 500 ppm copper, 50 ppb platinum, 230 ppb palladium and 60 ppb gold. Grab samples taken on the grid and to the north of the grid, returned consistently high values up to 3% copper and 2.6 grams combined gold and palladium per tonne.
Bright Star’s prospecting program has led the junior to believe that its soil anomaly may be larger than indicated. This data combined with its airborne geophysics suggests that there may be a bedrock source to the mineralization.
The junior plans to initiate an expanded soil sampling and trenching program over the South Olivine target area with the goal of enhancing the target’s size and including it in this season’s drill program.
