- Four known zones of mineralization: Emma, Emma NW, Lila and JoJo, all of which are easily accessible by road year round
- Lila, Emma and Emma NW are located directly on strike with Goldcorp's producing Cerro Colorado Mine which is situated 18 km away
- Surrounded by hundreds of successful placer miners
- Outstanding target for a quick and inexpensive exploration program due to its excellent infrastructure, road and water access and relatively moderate terrain
- There is a possible 15 km extension of the mineralization trend within the property
Initial Geochemical Results
Emma Zone: variable 1- 18 g/t Au
Lila Zone: 4.69 g/t Au and 24 g/t Ag
JoJo: 4.7 g/t Au and 65 g/t Ag
- "First pass exploration" composing of satellite imagery, reconnaissance mapping and prospecting
- Soil and silt geochemical sampling to prioritize further work
- "Second phase" including backhoe trenching, detailed rock sampling and selective geophysical surveys to outline areas for drill testing
Los Carlos is located in the prolific "Sonora Mojave Megashear" of Mexico which hosts over 50 gold occurrences and operating gold mines. La Herradura, La Choya, El Chanate and Cerro Colorado are among the important producing mines surrounding the Los Carlos Project. Some of the major exploration projects in the area include Mabel, Noche Buena and La Bolsa.
The historical workings targeting silver and gold in the shear structures present on the property. These workings have been conducted for the past 80 -- 100 years. The results of this activity indicate a range between 5 g/t - 30 g/t gold and 20 g/t - 200 g/t silver. Included in this data is a north-south sample line, each sample being 5.5 meters in length. Results include approximately 300 meters grading 0.96 g/t gold (assays cut to 3.0 g/t gold). Of the 54 samples, 11 assayed greater than 3.0 g/t gold with the highest grade being 26.0 g/t gold. Also included in the historical data, are assay results of several drill holes (reportedly done by a mine blast hole rig). Drill hole depths ranged from 24 to 105 meters (drilled at -45 degrees). All holes contained gold mineralization with several holes ending in good grade gold mineralization.
Partial assay results from sampling by the Company in the same area (excluding sampling the higher grade structures) indicate similar grades, such as 48.6 meters of 0.71 g/t gold on the south end and 26.0 meters of 0.51 g/t gold to the north end. Sampling of additional zones located at 300 meters and 1,000 meters to the north is complete. These chip and channel samples were taken over 250 to 300 meters wide mineralized zones.
Los Carlos is dominantly underlain by the Santa Ana Igneous-Metamorphic complex. This complex is made up of Precambrian basement rocks which are overlain by Jurassic volcanic arc and sedimentary rock assemblages. The area has undergone extensive tectonic activity and metamorphism from Late Cretaceous to early Tertiary periods. This activity includes thrust faulting, folding and greenschist metamorphism. In the Paleocene-age tectonic uplift, volcanism and syn-tectonic sedimentation also deformed the original Precambrian and Jurassic complex.
The observed metamorphic rocks of the property are highly foliated and include: micaeous schist, gneiss, meta-sandstone and meta-limestone. In the northeast section of the property an intrusion by Cretaceous to Tertiary-age granitic to granodioritic rocks have been documented along with a similar Tertiary aged granitic intrusion in the southwest. The observed lithologies are currently overlain by mid Tertiary-age conglomerate and sandstone and more recently Quaternary alluvium.
Numerous NW faults are intersected with multiple EW shears/fractures approximately 5 to 10 meters apart. The intersection of these two orientations appears to provide ample conduits for significant precious metal deposition. The rhyolite host rock between these E-W shears contains abundant veinlets and micro vienlets where gold grades range from 0.1 g/t to 2.0 g/t gold, again highly oxidized.
Los Carlos is an intermediate sulphidation, epithermal type system where gold/silver/lead veinlets are hosted in rhyolite porphyry. Currently, it contains 4 main zones of mineralization. Further exploration will be conducted to determine the extent of known zones and possible new zones of mineralization.
- Emma Zone
The Emma Zone consists of 4 known northwest striking parallel zones; these vary in width from 2 to 6 meters. The zones are characterized by east dipping zones of shearing, intense fracturing and quartz veining. These zones extend over a total width of 200 meters with gold values ranging from 1 g/t to 18 g/t.
- Emma NW Zone
Emma NW Zone is located directly on strike to the Emma Zone, approximately 1 km to the northwest. Similarly to the Emma Zone, shearing, intense fracturing, quartz veining along with limonite staining are present.
- Lila Zone
Lila zone is located approximately 3.5 km away from the Emma Zone, and is directly on strike with both the Emma and Emma NW zones. The zone contains visible secondary copper minerals, intense fracturing and shearing. Initial grab samples from the area contain up to 4.69 g/t gold and 24 g/t silver. These samples are also highly anomalous in copper, lead and zinc.
- Jo Jo Zone
The Jo Jo Zone is located approximately 2 km to the NE of the Lila Zone, with a paralleling NW strike to the Lila-Emma-Emma NW trend. As with the Lila zone, Jo Jo zone is characterized by parallel faults and shearing zones along with quartz veining and secondary copper minerals. Initial geochemical sampling returned with results of up to 4.7 g/t gold and 65 g/t silver and highly anomalous copper, lead and zinc values.
The currently known mineralized zones are exposed in past workings, however much of the zones are concealed. Future exploration programs will allow for determination of the full extent of these zones.
