Mountain Province Mining Inc. announces larger diamonds recouvered from 5034 pipe
VANCOUVER, British Columbia--(BUSINESS WIRE)--June 5, 1996-- Mountain Province Mining Inc., is pleased to report the results of the first quarter of the 100 tonne mini-bulk sample taken of the 5034 diamond pipe and processed by Canamera Geological Limited's dense media separation plant (DMS).
Diamonds with a weight of 75.9 carats were recovered from a total of 24.6 tonnes of processed kimberlite, for a recoverable grade of 3.09 carats per tonne. The kimberlite came from 9 drill holes into the Southern and Central parts of the pipe. The grade was found to be roughly uniform from drill hole to drill hole and from top to bottom in each of the drill holes, considering the small size of the sample.
The present results are an improvement over the results for the initial exploration holes, and larger stones have now been recovered as well. This is as expected because of the larger sample of kimberlite (24.6 versus 5.8 tonnes). Generally, for a diamond deposit, larger stones and greater values are obtained the larger the sample. There are 9 diamonds greater than 0.50 carats, 53 diamonds greater than 0.20 carats and 144 diamonds greater than 0.10 carats. The five largest diamonds are 1.89, 1.53, 1.03, 0.86 and 0.75 carats respectively. All five are clear, gem quality stones. The largest stone, originally estimated and reported at 1.2 carats (due to it being partly in kimberlite) was determined by weighing to be 1.89 carats after extraction from the kimberlite.
The grade of the diamonds greater than 2 mm in the largest dimension is 2.28 carats per tonne, which is an increase form the grade of 1.83 carats per tonne that was reported form the 5.8 tonnes form the initial exploratory holes. The DMS process does not recover all the diamonds smaller than 1.5 mm in size, which explains why the total grade is lower than the 5.36 carats per tonne for stones greater than 1 mm reported from the earlier results using the caustic fusion recovery process. Full recovery of these smaller stones is not considered economic, given their current low commercial value. The value of the diamonds will be determined once a representative sample is available.
The delineation of the 5034 is continuing. The size of the deposit has been increased to the South-West, Drilling on the Northern part on land is in progress. The deposit is calculated to be at least 20 million tonnes to a depth of 350 metres and is still open in several directions.
Exploratory drilling is continuing throughout the summer. Additional indicator mineral sampling will be conducted to better define additional drilling targets.
The AK property is held 50% by Mountain Province, 40% by Glenmore Highlands Inc. (ASE:GMH) and 10% by Camphor Ventures (VSE:CFV).
