Golden Hill/Mill City - two new gold zones discovered: Maclama Area, Cuba.CALGARY, Alberta--(BUSINESS WIRE)--March 20, 1997--GOLDEN HILL MINING CORP. (GHMC-CDN) and MILL CITY GOLD MINING CORP. (MIY-VSE) are pleased to announce an exciting new gold discovery based on the results of the exploration program of MacDonald Mines Exploration Ltd. (MMP MMP Matrix Metalloproteinase (enzymes related to tissue healing/remodeling and cancer cell metastasis) MMP Mixed Member Proportional (New Zealand electoral system) MMP Multi-man Publishing .A-ASE) at the Maclama gold prospect located 8 kilometres due west of the Golden Hill gold-copper deposits. Analytical results from 12 of 27 widely-spaced, cored, exploration drill holes have been received. These holes tested several targets defined in a systematic exploration program that included a 100 line-kilometre cut grid, geologic mapping, soil geochemistry, and ground geophysical surveys. The first 7 holes (M-01 to M-07) tested a large horseshoe-shaped induced polarization Induced polarization (IP) is a geophysical imaging technique used to identify subsurface materials, such as ore. The method is similar to electrical resistivity tomography, in that an electric current is induced into the subsurface through two electrodes, and voltage is anomaly, 800 metres in diameter, centered on a diorite diorite Medium- to coarse-grained igneous rock that commonly is composed of about two-thirds plagioclase feldspar and one-third dark-coloured minerals, such as hornblende or biotite. stock. Target IP-1 located on the east side of the anomaly returned an intercept in hole M-03 of 4.88 g/t gold over 3.50 metres (0.14 oz/ton over 11.5 feet). Target IP-2 located on the west side of the anomaly, hole M-05 intersected 0.80 g/t gold over 24.30 metres (0.02 oz/ton over 79.7 feet) and includes a 7.50 metre interval grading 1.22 g/t gold (0.036 oz/ton over 24.6 feet). The target IP-2 is also located on an 800 metre-long linear northeast-striking gold-in-soil anomaly containing up to 3.54 g/t gold (0.10 oz/ton).

Drill holes M-08 to M-12 tested the Maclama Hill area. All five drill holes intersected gold mineralization; including three intersections over wide widths. Hole M-11 returned 0.92 g/t gold over 53.96 metres (0.027 oz/ton over 177 feet) and included 6.10 metres that averaged 2.97 g/t gold (0.087 oz/ton over 20 feet). The Maclama Hill mineralization appears to be spatially related to the northeast-striking Mac Fault which has been traced for 2 kilometres along strike. The Mac Fault has a coincident gold-in-soil anomaly that is greater than 100 metres wide and 1200 metres long. As previously reported, surface grab samples and chip samples of outcrop along the anomaly have yielded values up to 11.0 g/t gold and 100.0 g/t silver. The Maclama Hill target has currently been drill tested on three parallel lines spaced 100 metres apart, and is open down dip and along strike at both ends. Company management is very encouraged by these new discoveries and is planning additional holes. These will be drilled once the current definition drilling program on the previously discovered oxide gold deposits at Golden Hill has been completed. The two newly discovered Maclama gold zones are a very significant potential addition to the at-surface heap-leachable reserves delineated at both the Florencia Sector deposit and at the large-tonnage Golden Hill deposit. The potential to combine processing of the presently indicated resources at these three nearby deposits indicate substantial economies of scale with attendant grade and production rate consequences. Analytical results for the remaining holes completed at Maclama will be released as soon as they become available. Operator MacDonald Mines is conducting the ongoing exploration program at the Golden Hill epithermal gold discovery, in east-central Cuba, on behalf of partners GeoMinera S.A., a Cuban state agency, and Golden Hill Mining Corp. Mill City currently owns approximately 42 percent of the Shares of Golden Hill.
