Manhattan Minerals Corp - Manhattan Minerals Tambo Grande assay results Manhattan Minerals Corp MAN Shares issued 24,264,523 1999-06-17 close $5.45 Friday Jun 18 1999 Mr. Graham G. Clow reports: Manhattan is pleased to announce the results of gold and silver assays carried out on the resampling of core from 21 holes on the TG-1 deposit, drilled by BRGM in 1979/80. TG-1 is a volcanogenic massive sulphide deposit hosting an inferred resource in the sulphide zone of 42 million tonnes grading 2 per cent copper, 1.5 per cent zinc, 38 grams silver per tonne and 0.4 per cent lead. This release summarizes the results of assays of drill core from the oxide cap overlying the sulphide zone. Prior to this resampling program by Manhattan, the gold content in both the oxide cap and the sulphide zone had not been systematically quantified. The company expects to release assay results from the BRGM sulphide zone drilling within the next 10 days. The overall weighted average of the intervals in bold in the table below is 4.93 grams gold per tonne and 98.8 grams silver per tonne, over 11.5 metres true width. The overall weighted average over the total oxide thickness is 3.06 grams gold per tonne and 62.4 grams silver per tonne, over 18.3 metres true width.

Core from holes 14 and 15 was used previously by BRGM for test work. The BRGM drilling was carried out on a hole spacing ranging from 50 metres to 150 metres, extending over an area of approximately 700 metres by 300 metres. All holes except TG-1 were vertical. The core was held in secure storage by BRGM until July, 1998, when it was transferred to Manhattan's secure core logging facility in Piura, Peru. The samples were taken at one-metre intervals from HQ (63 millimetre) size whole core. The core was halved and the remaining portion kept for future analysis, if required. Assay results are reported as uncut. Out of a total of 422 samples in the intervals reported above, two samples were greater than 30 grams gold per tonne, the highest being 80.97 grams per tonne over 0.4 of a metre. The oxide cap is composed of a stratified gossanous sequence overlying the sulphide zone. The base of the sequence is typically a ferruginous baritic sandstone, grading upward into oxidized and altered rhyolite, a silicified and locally barite bearing goethite-cemented breccia and, finally, upward into a clay rich gossan. The gold concentration increases with depth in the oxide cap and appears to overlie base metal concentrations in the underlying sulphide zone. The oxide cap is overlain by approximately 15.4 metres of sandy overburden. Assay results have yet to be received from the new Manhattan drilling (see Stockwatch June 17, 1999) to determine whether the oxides that continue beyond the BRGM defined limits are gold bearing. Sampling methods, preparation and analytical procedures were carried out under a quality control program designed by MRDI Canada, a division of H.A. Simons Ltd., and ITS-Bondar Clegg Ltd. The samples were prepared by ITS-Bondar Clegg at Manhattan's core logging facility and then transported by ITS-Bondar Clegg for analysis in Canada. Gold concentration was determined by standard fire assay methodology. Silver concentration was determined using total acid digestion with AA finish. The quality control program included the insertion of duplicates, standards and blanks, in addition to ITS-Bondar Clegg's standard quality control program. ITS-Bondar Clegg is registered to ISO 9002 standard and all assays are certified by B.C. certified assayers. (c) Copyright 1999 Canjex Publishing Ltd. canada-stockwatch.com
