Junior Taseko Mines (TKO-V) is pleased with results received from a program of large core diamond drilling on the Prosperity project near Williams Lake in central British Columbia.
The results compare favorably with the average grade of the previously established minable reserve of 675 million tonnes grading 0.43 gram gold per tonne and 0.24% copper.
Some 107 holes were drilled in a program spanning 49,462 metres. Of that total, Taseko drilled 6,760 metres in 33 holes to obtain geotechnical and environmental measurements for engineering studies of potential locations for rock storage, tailings impoundments and other mine facilities.
Results from the latest drilling include: hole 248, which returned 446 metres grading 0.53 gram gold and 0.24% copper; hole 254, which returned 533 metres grading 0.52 gram gold and 0.33% copper; hole 256, which returned 372 metres of 0.71 gram gold and 0.38% copper; hole 258, which returned 477 metres of 0.62 gram gold and 0.39% copper; hole 262, which intersected 404 metres of 0.54 gram gold and 0.27% copper; hole 264, which returned 446 metres grading 0.42 gram gold and 0.29% copper; hole 267, which intersected 545 metres of 0.52 gram gold and 0.35% copper; and hole 270, which returned 348 metres of 0.47 gram gold and 0.29% copper.
Engineering studies are attempting to determine the benefits of an expanded mining and milling operation of 90,000 tonnes per day, up from 60,000 tonnes per day foreseen in a 1994 prefeasibility study by Kilborn Engineering. That earlier study called for a mine with a stripping ratio of 1.57-To-1, and a mine life of 31 years.
Taseko has contracted Kilborn to provide a bankable feasibility study based on programs now under way and data collected to date.
