MONTREAL--(BUSINESS WIRE)--Oct. 30, 1996-- DYNACOR MINES(ME DYN. ) Mines Dynacor confirmed that the Carnero and Principale veins on its Acari property in Peru have high levels of gold content.

Sampling has yielded results similar to those previously obtained by our Peruvian partners. The two veins have always been mined on a small scale, at the surface or in drifts, and over short distances. In 1995, Acari produced 5,500 ounces with an average grade of 32g/t Au (0.93 oz/t Au).

Prospectors have panned for gold at the surface of these veins since pre-Columbian times-a fact that indicates excellent potential for the discovery of other veins. Because of the processing methods used, gold washers of the past were unable to recover more than 50 percent of the gold in the ore extracted, and ore grading less than 17 g/t Au (0.5 oz/st Au) was rejected. GEOLOGY

The Carnero vein has an orientation of 1350 and dips almost vertically to the west. Its width reaches 2 metres in some places, and its elevation ranges from 900 to 1,450 metres above sea level.

Carnero has been identified visually over nearly 1,200 metres, and some geological observations lead us to believe that it may cover more than 1.2 kilometres. Some of the samples taken have graded from 26.96 g/t Au (0.78 oz/t Au) to 143.5 g/t Au (4.16 oz/t Au)(1).

The Principale vein can be seen to run continuously over a distance of 1,200 metres and has a total length of more than 4 kilometres. This formation, which contains several veins and veinlets, measures up to 1.5 metres in width. The Principale vein is located in a shear zone more than 4 metres wide in places.

Twenty-one samples were taken systematically at one-metre intervals at Level 2 along the width of the Principal vein, yielding an average of 42.79 g/t Au oz/st Au). These results corroborate To support or enhance the believability of a fact or assertion by the presentation of additional information that confirms the truthfulness of the item.

The testimony of a witness is corroborated if subsequent evidence, such as a coroner's report or the testimony of other the bulk sampling of 1,200 tons for metallurgical purposes in 1995, when an average grade of 32 g/t Au (0.93 oz/st Au) was indicated.

Acari is located in the Nazca-Ocona gold-bearing belt, which is 350 kilometres in length and 40 kilometres in width. Geologically, the mine consists mainly of granodiorite granodiorite

Medium- to coarse-grained rock that is one of the most abundant intrusive rocks. It contains quartz and is distinguished from granite by having more plagioclase feldspar than orthoclase feldspar; its other mineral constituents include hornblende, biotite, and interspersed with coarse diorite diorite

These veins, which are several kilometres long and as much as 2 metres wide, show grades of 6.00 oz/t Au and higher.

Mapping will be undertaken soon to identify other veins, since the Acari property has never been systematically explored. Several generations of dykes of various ages and compositions are present near the mineralized zones.

Mines Dynacor inc. is a mining company whose short-term objective is to increase gold production at its Acari mine in Peru. The Company is determined to acquire new gold-bearing properties for the purpose of commercial production.
