MAPLE MINERALS COPPER-GOLD-SILVER-MOLYBDENUM DISCOVERED ON HAMLIN PROPERTY, SHEBANDOWAN CAMP
Mega Uranium Ltd. has provided an overview of the progress of its division, Maple Minerals.
Sheldon Inwentash, chief executive officer of Mega, comments on the progress of its Maple Minerals division: "We are delighted with the progress of Maple Minerals to date on the Hamlin property, who are now vigorously pushing ahead with a drill program in October and November to develop an understanding of the deposit within the wider Shebandowan camp. The results of this extensive trenching program now enable Maple Minerals to move ahead with its exploration."
Geological details
A substantial zone of copper-bearing sulphide mineralization has been exposed by trenching on the Hamlin property for a strike length of 800 metres and appears to continue another 1,200 metres as outlined by IP resistivity geophysical surveys.
Samples taken from a rusty zone in brecciated rhyolite during geological mapping identified a copper-gold occurrence on the sulphide trend that assayed 1.47 per cent copper and 4.88 grams of gold per tonne. As a result, an extensive trenching program was initiated on Sept. 5 to expose other target zones. Assays of a series of random samples taken roughly at 10-to-15-metre spacings along the trend, with some samples taken to the side within a 30-to-50-metre-wide expanse of rusty rhyolite, are presented below.

These samples represent four trenched areas in 100-metre length sections, along a 525-metre strike length on the west end of the two-kilometre-long trend. Assays results for other samples taken along strike are pending. Chalcopyrite with occasional bornite occurs with pyrite, magnetite and chlorite alteration, as well as pink potassic alteration. Molybdenite (MoS2) has been noted in some samples with values reaching 1,635 parts per million Mo (3.6 pounds). Chalcopyrite mainly occurs as fine disseminated zones in the rhyolite with occasional stringers but sometimes forms massive sulphide lenses up to 0.5 metre in the breccia.
The mineralized zone is interpreted to be a stringer zone associated with a volcanogenic massive sulphide (VMS) system with an overprint by a larger alkali intrusion that causes the pink potassic alteration and molybdenum occurrences within the zone. Brecciation of the volcanics may be in part caused by the fine-grained syenite-type alkali intrusives but mainly appears to be related to the intense chlorite that forms the matrix to the breccia. Silver values correlate with the copper supporting the interpretation that a stringer VMS setting may have initially been in place prior to the alkali mineralizing event that could have introduced additional gold as well as molybdenum. Drilling commenced on Oct. 18, 2005, to test the induced polarization and electromagnetic anomalies.
Base metal and silver values (copper, molybdenum and silver) were determined by induced coupled plasma (ICP) after an aqua regia acid digestion. Assays exceeding 100 grams of silver and 5,000 parts per million (0.5 per cent) copper were repeated using multiacid digestion and atomic absorption (AA). Check assays were run on every 10th sample as well as high values were repeated. Preparation and assaying of the samples outlined in this news release were carried out by Accurassay Laboratories in Thunder Bay. Additional check assays are being run in an independent lab using ICP as part of the continuing program and quality control process.
Gold values were determined by fire assay extraction on 30-gram samples followed by an AA finish.
The Hamlin property is owned 100 per cent by Maple Minerals and East West. The project is being supervised by R. Middleton, PEng, who is the qualified person and responsible for quality control of the assaying and reporting.
