Our core El Dorado-Monserrat project (approx. 8,000 hectares) is situated adjacent to AngloGold Ashanti’s major Cerro Vanguardia gold mine and hosts over 15km of outcropping, low sulphidation epithermal gold-silver mineralized veins associated with identified domal features. A significant element of the property is covered by a late flow of olivine basalt.
It is considered likely that a geophysical examination of these areas (notably to the north of the Main Veins and Monserrat West targets as well as the Judite Trend) will lead to the identification of further targets as well as strike extensions of others.
The El Dorado and Monserrat concessions were initially claimed by Dr. Ricardo Auriemma in 1986 and have been the subject of a number of exploration campaigns conducted by different operators in joint venture over the past 30 years. Most recently, prior to its acquisition by Teck, Aur Resources’ gold division conducted an extensive surface (including over 64 km of trenching) and shallow drilling (totalling some 15,000 metres) campaign over certain of the principal targets on the project.
The Company has identified six high quality targets on El Dorado-Monserrat, namely:
The Main Vein System
A N-S trending epithermal vein complex with over 6km of outcropping veins hosting defined high grade veins with average widths (so far only tested to a depth of approx. 50 metres) of approximately 1 metre within wider mineralized alteration zones giving an average mineralized width of over six metres
In the south, the system swells to over 1.5 km in width, in major conjugate splays hosted within extensive breccia zones, which offer the additional potential for large tonnage, low grade mineralisation
Mineralisation is open in all directions
In the north of the system, trenching and drilling by Aur Resources on the Camila C section yielded encouraging intersections both on surface and to an average vertical depth of c.50 metres:
• Channel samples taken at 5-20m intervals averaged 18.45 g/t Au and 417.0 g/t Ag
• 25 trenches over widths ranging from 1.6m to 14.05m yielding grades of up to 13.78 g/t Au and 224.6 g/t Ag
• An earlier drill hole on the related Ines rhyolite target intersected 2.3m with 37.25 g/t Au and 2,296.38 g/t Ag
• Aur Resources’ work resulted in significant interceptions at shallow depths including
Located to the West of the Main Veins, Monserrat West is a concealed rhyolitic dome with related vein structures. Aur Resources drilled approximately 6,000 metres which intersected significant gold and silver values and provided further indications of high level, low sulphidation epithermal mineralization
• An early stage target comprising over 4km of outcropping veins with similar characteristics to the Main Vein complex, including silicified andesite cut by anastomosing quartz veinlets with extensive conjugate features
• LAG sampling anomalies in antimony, arsenic and mercury suggest the presence of a concealed high level epithermal system Monserrat East Regional Topography
Cerro la Herradura
• A large (approx 2km2) zone of alteration surrounding a volcanic fusion centre characterised by approx 400m2 outcrop of mineralized breccia, which has been channel sampled and returned grades of up to 30g/t Au
• Related field of outcropping and indicated quartz veins La Herradura Outcrop
• Over 4 km of outcropping veins trending East-West away from the Herradura Prospect. Trenching and limited drilling (to date) has indicated the signatures of a high level epithermal system
• Beethoven North comprises a series of targets to the north of the outcropping veins which have the potential to represent a series of parallel, but non-outcropping structures Beethoven Outcrop
The Judite Trend
• A strong NNW trend identified through windows in the basalt on the Judite property where Chon Aike outcrop remains uncovered. Parallel to the structure that runs through the heart of the Cerro Vanguardia mine
• A series of other targets representing parallel structures to the Judite Trend have been identified as having potential to host mineralization
• In addition to these six areas of focus, management has identified certain other areas on the property which offer potential to host parallel systems or extensions of systems already identified.
• These include the area to the north of the Main Veins and Monserrat West, which is covered by a thin cover of basalt and the areas between the Main Veins and Monserrat West and East where quartz float and jasper on surface present indications of concealed systems.
