overview | past work
June 11th, 2008: Almaden is pleased to announce that it will conduct a detailed stream sediment sampling program the Munro Lake porphyry project. There is little exposure of outcrop on the property which has hindered geologic mapping and past exploration efforts. A new interpretation of the available data has identified possible extensions to the mineralization. Almaden is planning a field program to investigate this potential and to design further diamond drilling. Almaden has initiated the current program to test the potential of the targets identified. Almaden is also seeking a suitable partner with the requisite technical abilities to advance this exciting molybdenum project. [read more +]
The 100% Almaden owned Munro Lake porphyry molybdenum-copper-silver project was acquired in 1986 by the company through staking. The project is near Summerland,
British Columbia and is road-accessible.
The project is located roughly 20 kilometers south of the Brenda molybdenum-copper porphyry deposit. Almaden believes that the mineralization at Munro Lake to be genetically similar to that mined at Brenda where production began in early 1970 with reserves of 160,556,700 tonnes grading 0.183 per cent copper and 0.049 per cent molybdenum. The Brenda mine officially closed June 8, 1990.
Work to date on the project include ground geophysics (induced polarization and magnetics), soil geochemistry and diamond drilling programs have been carried out.
In 1996 and 1997 Almaden completed 12 diamond drill holes spaced over roughly 6 kilometers. These holes were designed to test a high chargeability feature interpreted to represent sulphides emplaced within equigranular to porphyritic intrusive rocks. Most of these holes intersected anomalous copper, molybdenum and silver values, the most important of which are tabularized below. These intersections include a 14.8 meter interval in hole 96-3 that averaged 0.10% Molybdenum (Mo), 0.05% copper and 15.1 g/t silver.
