Some of the statements contained in this website are forward-looking statements. Forward-looking statements are not historical facts and are subject to a number of risks and uncertainties beyond the Company’s control, including, but not exclusively, statements regarding potential mineralization, exploration results, completion of work program and studies, and future plans and objectives of the Company. Resource exploration, development and operations are highly speculative, characterized by a number of significant risks, which even a combination of careful evaluation, experience and knowledge may not eliminate, including, among other things, unprofitable efforts resulting not only from the failure to discover mineral resources but from finding mineral deposits which, though present, are insufficient in quantity and quality to return a profit from production.
Grade and tonnage information for the historic Lousal, Caveira, and São Domingos Mines has been collected from a variety of sources, all compiled before the existence of National Instrument 43-101. Information provided must be considered to be speculative in nature, and must not be used in any sort of resource or reserve calculations. The information is meant only to give the reader some idea of what may be possible in the Pyrite Belt.
For Lousal, the numbers are compiled from numerous historic operator production reports. These reports are incomplete, but they indicate that the mine hoisted about 238,000 metric tonnes per year from 1953 through its closure in 1988. The production estimate extrapolated an annual production of 238,000 metric tonnes per annum back to 1900, and is believed to provide a reasonable maximum production estimate. No mining estimates have been made for the Caveira Mine, and the Sesmarias discovery has not been mined. Avrupa’s QP has reviewed the data and has verified its existence and accuracy. The historic resource estimates are contained in a report authored by Leistel et al in 1998, estimated a global mineral inventory of 50 Mt grading 0.7% Cu, 0.8% Pb, and 1.4% Zn for the Lousal Mine. The Caveira Mine does not have any known global mineral inventory. The Sesmarias discovery has limited scout drilling and no global mineral inventory.
For São Domingos, the resource estimate was compiled from historic reports. The 1963 Mason & Barry Annual Report indicates that nearly 22 million metric tonnes had been extracted during 106 years of production, and the reserves were expected to run out at the end of 1965. No newer resource estimates have been done for the São Domingos Mine. The work needed to provide a modern estimate has not been done, but would include re-analysis of historic core, drilling, sampling, and three-dimensional modeling. Avrupa’s QP has reviewed the data and has verified its existence and accuracy.
The work needed to provide a modern estimate has not been done, but would include re-analysis of historic core, drilling, sampling, and three-dimensional modeling. Avrupa’s QP has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves. The Company does not treat the historical estimate as current mineral resources or mineral reserves.
Present production information concerning active operations in the Pyrite Belt has been collected from each mine operator’s website, or from widely disseminated news releases.
Qualified Person: Mr. Paul W. Kuhn, M.S., C.P.G., has acted as the qualified person as defined in National Instrument 43-101 for this disclosure and supervised the preparation of the technical information on this website.
