The Montaña de Oro project totals 25,983 hectares and is located in the Sierra Madre Gold-Silver Belt of northwestern Mexico, a prolific gold-silver belt with a history of mining dating back several hundred years. Montaña de Oro lies in an ENE trend which includes Pan American Silver’s Alamo Dorado mine and Goldcorp’s El Sauzel mine. A total of 22 targets have been identified to date, including: 17 areas of gold mineralization, a carbonate replacement discovery, and 4 undrilled copper porphyries. The property is underlain by the Guerrero Terrane which consists of Late Jurassic to Early Cretaceous andesitic flows interbedded with andesitic tuffs and minor carbonate sedimentary rocks and sandstone. There are three distinct styles of mineralization: low sulphidation Au-Ag, porphyry-related Cu-Mo-Ag mineralization with an Au signature, and contact metasomatic skarn deposits with distinct base metal (Pb+Zn) tenors. This is a favorable location for mine development with respect infrastructure and local resources. Historical work includes 150 drill holes for 39,833 meters by West Timmins Mining.
La Dura West (Cu-Ag)
The La Dura West prospect features copper-silver porphyry related geochemistry, and alkaline style of alteration. The zone, as it has been drill tested over approximately 1,600m x 600m, north to south. Cu-Ag porphyry signature is composed of multiple intrusions: tonalite, microtonalite, quartz monzonite porphyry, andesite porphyry and granodiorite
Historical drill highlights include:
La Concepción (Zn-Cu-Ag-Au)
The La Concepción prospect is a carbonate-replacement massive sulphide / breccia Zn-Cu-Ag-Au system located within the La Dura West prospect. Mineralization occurs as massive sulphide replacements floored by Au-Ag rich siliceous breccias. The zone, as it has been drill delineated to date, is approx. 200m x 100m, though offset by faulting. There is a strong IP anomaly associated with fault offset to northeast. The breccia zone to the south has strike length in excess of 600m exposed with widths of 50 to 150m. Highlights from historical drill holes:
Abundant historic placer gold associated with IP anomaly and projected massive sulphide fault offset.
La Dura East (Zn-Ag-Cu)
The La Dura East prospect is a Zn-Ag-Cu Skarn located 1.4 kilometers east of La Concepción on the periphery of the large La Dura West porphyry copper system. Limestone-hosted alteration can be traced for 2.5km at surface, then 0.8km further south with Cu-Au and magnetite skarn
Three areas of interest have been identified through past drilling (Lake Shore Gold): La Dura North, Nariz, and La Dura South.
El Rodeo (Au-Ag)
The El Rodeo prospect is made up of a bonanza grade epithermal vein cluster with multiple targets. The zone is comprised of epithermal stockworks, breccias and a network of quartz veins hosted in andesite. It is located mainly along the regional scale El Rodeo fault system which include multiple sites of high-grade past production. Targets include:
The Suby prospect is a large (3,600m x 1,000m) copper-gold-silver-bismuth mineralized trend associated with anastomozing quartz-sericite veins, aplite dikes, and granite quartz porphyry intrusive, granodiorite host, also anomalous in Mo, W, and Pb. Work to date includes 36 short hand dug trenches, N-S soil grid, mapping & rock chip sampling. Mineralization extends under post-mineral basalts and can be found on north side of post-mineral cover, extensive system.
El Zataque (Au-Ag)
The El Zataque prospect is located along the southern extension of the regional scale El Rodeo fault system, approximately 5km south of the El Rodeo discovery. Mineralization at surface consists of strongly weathered, sulphide-rich silicified andesite, rhyolitte and quartz diorite. The leached zone is 1.5km by 0.8km in size and is evident in many outcrops and a prominent area of stressed vegetation over the entire area. Historical work includes IP conducted in 2007, core drilled in 2007 and 2008 with 13 holes intersecting <500ppm Cu in magnetite-biotite altered rocks.
La Mora (Au-Cu-Ag)
The La Mora prospect is a conceptual Cu-Au IOCG. Mineralized zones are found in altered and sheared microtonalite. There is biotite-magnetite alteration and abundant copper carbonates. Wider alteration zone is 1.5km in diameter, with the core approx. 500m long along strike by 100m across. Preliminary sampling has returned up to 0.69g/t Au, 7.1g/t Ag and almost 1% Cu. A total of 10 samples collected during 1 day trip
The Baboyhui prospect is located within an historic placer gold area 7km NNW of La Dura. Historical sampling returned values up to 2.13g/t Au, 143g/t Ag and 6.55% Cu. A zone of quartz-sericite and hematite alteration associated with a quartz monzonite intrusive produced a colour anomaly measuring 4.5km by 2.5km. Historic soil ridge & spur sampling, rock chip sampling, no mapping other than 250k gov. Never drilled
The Chapote prospect was previously core drilled by Consejo in 1988, identifying an Au-Ag-Cu bearing skarn with 10m of 0.24g/t Au, 9g/t Ag, and 0.11% Cu along with several 1m intervals in diorite running up to 1.28g/t Au, 23g/t Ag, and 0.2% Cu. It is located within an historic placer gold area. Nine samples returned values greater than 1.0g/t Au, and ridge and spur sampling shows Cu-Au association. Other historical sampling returned values up to 3.3g/t Au, 72.2g/t Ag, and 2.32% Cu. The known zone of alteration measures approximately 2km in diameter
