30,000 Meters Of Core Drilling Planned At Douay
MONTREAL - Aurvista Gold Corporation reported the start of the Phase 2 Core Drilling Program on the Company's Douay Gold Project . The exploration activity objective is to demonstrate the continuity and grade of the newly predicted gold corridors linking the known 9 higher grade gold zones and 2 lower grade gold zones within and outside the defined 10 km by 3 km Adam Creek Gold Deposit, potentially leading to an increase in the quantity and quality of the mineralization.
Jean Lafleur, President and CEO of Aurvista said, "After more than 40 years of exploration on Douay, including the last few by Aurvista, we have finally arrived at a major crossroad. The previous path has included nearly 200,000 meters of drilling in more than 700 holes, ground and airborne geophysical surveys, infrastructure construction, all leading to the discovery of higher and lower grades gold lenses. The gold mineralization at Douay occurs within 9 individual E-W shears and 3 subparallel structural domains inside a 10 km by 3 km corridor of a 20 km long segment of the Casa Berardi Deformation Zone."
Lafleur added "Douay has always lacked a single cohesive geological exploration model to explain in part why there is gold mineralization and its distribution. After 6 months of re-evaluating the entire database, Aurvista developed a new geological model and can now proceed with focussed multi-staged diamond drilling into a number of target shears and structural domains. These domains could potentially have an impact on the ultimate dimension of the gold system and mineral resources. There is a significant potential of discovering more gold mineralization in addition to our existing multi-million ounces in mineral resource estimates. Aurvista will now begin testing the Adam Creek Gold Deposit with a major 30,000 meter drill campaign."
A total of 9 Priority Targets, identified as T1 to T9, were outlined within the Deposit during the Phase 1 Detailed Targeting Program. These Targets will be tested by more than 70 drill holes totaling 30,000 meters in three sub-phases.
The Phase 1 Detailed Targeting Program (has led Aurvista to predict gold and possible massive sulphides occurrences on Douay. The Phase 1 Program's objective was to define and correlate the known gold mineralization chemistry and alteration mineralogy to the geological and geophysical signatures that could then be utilized to predict new gold mineralization. The Phase 1 Program was successful in determining that the nature, distribution and metal history led to one single gold deposit, the Adam Gold Deposit, exhibiting similar host rocks, alteration styles and structural fabric.
A combination of iron-rich rocks with iron carbonate and sulphide alterations produced higher and lower grade gold mineralization in association with E-W shear zones and cross-structures, but more importantly there is a link of the known mineralization to specific shears, potentially predicting where to find additional gold mineralization. In terms of the overall potential, there are two distinct but overlapping metal signatures at Douay, the first is a primary Volcanogenic Massive Sulphide or VMS of Copper-Zinc affinities crosscut by a secondary shear-hosted gold system. This interpretation is very similar to the Doyon-Bousquet-Laronde mining camp located 100 km S-SW of Douay, along the Cadillac Larder Lake Deformation Zone.
Regional deformation at Douay produced and enhanced the crisscrossing network of NW-SE, NE-SW and E-W structural fabric which led to the eventual emplacement of porphyries and subsequent gold mineralization within the known 10 km by 3 km Adam Gold Deposit and possibly towards the east and west. There are several subparallel shears hosting the 8 higher grade and 2 lower grade gold zones with a significant potential of discovering more gold mineralization in addition to our existing mineral resources based on the number of shears, structural domains and junctions.
