Initial Despinassy ResultsAlto Ventures Ltd.: Continued Intercepts of Good Grade and Thickness at Despinassy Gold Project, Quebec
2/16/05
VANCOUVER, BRITISH COLUMBIA, Feb 16, 2005 (CCNMatthews via COMTEX) --
Alto Ventures Ltd. (TSX VENTURE:ATV) is pleased to announce initial results of its ongoing 5,000 metre drill program at its Despinassy gold project near Val d'Or, Quebec. Results from five holes drilled on the DAC deposit confirm that each hole intersected wide intervals of shear hosted gold mineralization, up to 33 metres thick, containing multiple, high grade quartz veins. The best results from each of the holes include:
14.6 g/t Au over 3.7 metres (including 51.2 g/t Au over 1.0 metre);
7.0 g/t Au over 7.2 metres (including 16.4 g/t Au over 2.7 metres);
6.7 g/t Au over 3.1 metres (including 14.0 g/t Au over 1.2 metres);
6.4 g/t Au over 5.9 metres (including 22.0g/t Au over 1.4 metres); and
45.8 g/t Au over 0.4 metres
The style of gold mineralization at Despinassy is typical of "greenstone" gold deposits mined in the Abitibi Gold Belt. Anomalous gold occurs within the Despinassy Shear Structure that is over 200 metres wide and drilling to date has traced gold mineralization for 5 kilometres along strike. Four parallel zones (Zones 1, 2, 3, and 4) of intense alteration and quartz veining have been intersected in the DAC deposit (formerly Area One).
Zone 2 has been confirmed to be well mineralized and the most continuous of these zones with intercepts of:
3.4 grams gold per tonne over 14.0 metres;
1.97 grams gold per tonne over 28.0 metres;
2.33 grams gold per tonne over 25 metres; and
0.58 grams gold per tonne over 33.2 metres.
Zone 3 has also been confirmed to be continuous and well mineralized with results including:
1.2 grams gold per tonne over 13.9 metres; and
2.0 grams gold per tonne over 14.7 metres.
Sections of high grade quartz veins, which range in width from 0.3 metres to almost 10 metres occur within these zones. Alto is encouraged by the continuity of these gold zones and the grades of gold mineralization encountered to date. Detailed results for DES05-64 to 68 are presented in the accompanying table.
The principal objective of these drill holes is to initiate the estimation of an inferred resource in the DAC deposit. The current holes were drilled 25 metres apart horizontally in 25 to 50 metre vertical step-outs. In addition, Alto is drilling on IP anomalies up to three kilometers to the west along the Despinassy Shear Structure that were identified in a fall geophysical program. Previously undrilled Cameco IP targets, two kilometers to the east, will also be tested in the current program.
Quality Assurance/Quality Control
Core processing included descriptive logging and selection of samples for analyses. The cores selected for analyses were sawed in half and one half was sent to a commercial laboratory and the other half retained for future reference. Gold assays were performed at ALS Chemex Laboratories in Val d'Or Quebec. The gold assaying method uses a standard Fire Assay with AA or Gravimetric finish technique, as requested by the Company, on 30 grams sub-sample taken from a 250 gram split off the raw sample.
The Laboratory was instructed to prepare and analyze a second 250 gram split from the reject for those samples that indicated greater than 2 grams gold per tonne on the initial analysis. Commercially prepared standards were inserted every 25 samples to ensure precision of the results. The results reported represent composites using weighted averages of all analyses performed on each specific sample. Mike Koziol P.Geo., Alto's Vice President of Exploration, is the qualified person supervising the drill program.
About Alto Ventures Ltd.
Alto is acquiring Cameco's 70% interest in the Despinassy Joint Venture from Cameco Corporation through a series of cash and share payments totaling $700,000 over a five year period. Under terms of an agreement with Commander Resources Ltd., Alto's 30% partner in the project, Commander is being carried for the first $500,000 of the current program. Alto is the operator.
Alto is a gold exploration and development company with a portfolio of mid to advanced stage exploration properties in the Canadian Shield. The Company is focused on exploration and acquisition of mineral properties in the Abitibi greenstone belt in Ontario and Quebec as well as in historic gold producing districts in the western Superior Province of Ontario and Manitoba. There are currently 42.5 million shares outstanding.
