Projects Violin 2
Violin 2 is Alphamin's most advanced project in Mexico. The property situated in the municipalities of Mochitlan and Quechultenango. The project area is comprised of 4 claims totalling 11,026 hectares in area. Alphamin's wholly owned Mexican Exploration subsidiary, Exploraciones La Plata, S.A. de C. V., has 100% ownership of the 4 claims with one of the claims, Violin 2, being subject to a 3% net smelter return.
There is an excellent network of roads and trails crossing the property, providing good access.
At Coaxtlahuacan Norte an annular or donut-shaped copper-in-soils anomaly, defined by copper values greater than 210 ppm, is 720 by 820 metres in size (~50 hectares) and is open to the north and west. The area is underlain by Tertiary age quartz diorte and porphyritic quartz monzonite intrusives. Grab samples of surface mineralization consisting of copper and iron oxides have assayed up to 2.8% copper, 54.8 grams/tonne silver and 0.31 gm/t gold.
On the Coaxtlahuacan grid gold in soil ranges up to 2,160 ppb and copper up to 3,810 ppm in the southern part of the grid. The anomalous area as defined by the 210 ppm copper contour is 49 ha in area and is open to the south. Zones anomalous in gold, as defined by areas within the 120 ppb gold contour, coincide in part with the copper anomaly and are situated immediately to the north of the copper anomaly in what appears to be a fault bounded block of the intrusive. Anomalous gold zones within the coppper anomaly total 18 hectares in area; the gold zone to the north totals 30 ha in area. Grab samples from surface exposures and road cuts in the copper anomalous zone have assayed up to 1.37% copper, 5.56 g/t gold and 13.5 g/t silver.
To the east of the Coaxtlahuacan grid on the Mezcaltepec grid is a strong silver-lead-zinc anomaly that forms a southerly trending arcuate zone 7.5 kilometres long and up to 1.4 kilometres wide. The area is underlain by sediments of the Middle Jurassic age Tecocoyunca Group. Lead in soils ranges up to 32,600 ppm; zinc to 3,600 ppm; silver to 60.2 ppm and copper to 621 ppm. There are several known mineral occurrences within the anomaly. Judging from the nature of mineralization found at the known occurrences, the soil anomalies are interpreted to reflect epithermal silver-lead-zinc-barite veins within the underlying metasediments and metavolcanics. Assays of selected character grab samples of mineralization from La Fortuna mine dump ranged from 40.1 to 2,042 grams/tonne silver, 1.97% to 20.9% lead, and 0.32 to 18.76% zinc. At La Estrella workings, assays of selcted dump samples ranged from 396 to 468 grams/tonne silver, 10.93% to 13.76% lead and 0.01% to 0.12% zinc. There is a strong northwesterly structural control to the mineralization at both La Fortuna and La Estrella. At the Gaudalupe mine workings, chip samples ranging in width from 0.5 to 1.5 metres ranged from 72.5 to 329 grams/tonne silver, 1.92% to 13.68% lead and 0.29% to 1.56% zinc. At the San Andreas prospect, channel samples across 0.5 and 1.0 metres returned assays of 354 and 676 grams/tonne silver, 16.72% and 15.76% lead and 5.2% and 0.07% zinc respectively.
To the south of the Mezcaltepec grid, on the San Isidro grid, a strong silver-lead-copper-zinc and gold anomaly occurs. The anomalous zone is 3.0 by 2.4 kilometres in size with silver values ranging up to 51.3 ppm; lead up to 21,860 ppm; copper up to 2,109 ppm and zinc up to 20,070 ppm. The polymetallic soil anomalies on San Isidro are underlain by limestones and marbles of what is believed to be part of the Xolapa Complex. It is speculated that the anomalies may be caused by underlying VMS mineralization in the Xolapa complex and/or by chimney and manto (CRD) mineralization in the limestones. Follow-up prospecting and rock sampling in the soil anomaly has located sulphide gossans, channel sample of which have assayed from 8.2 to 86.5 grams/tonne silver, 0.1% to 1.08% lead and 0.29% to 8.15% zinc over intervals of 0.3 to 0.5 metres.
At the southern end of the property on the Piedra Iman grid, soil sampling has defined polymetallic anomalies in a 2 by 2 kilometre area. Copper in soils ranges up to 1,667 ppm, lead to 2,686 ppm, zinc up to 1,981 ppm and silver up to 27.7 ppm. The area is underlain by metasediments and metavolcanics of the Xolapa complex. The soil anomalies are associated with exposures of metarhyolite and enigmatic hematite matrix breccias that are speculated to form caps to underlying VMS mineralization.
Management is very pleased with the results of the work conducted on the Violin 2 project area, which it feels demonstrate the potential for the property to host economic mineral deposits. Alphamin intends to close off existing soil anomalies by completing soil sampling around the existing grids. Selected areas will be tested by geophysical ground surveys (induced polarization, electromagnetic and magnetic) in order to better define drill targets. In addition, detailed geological mapping and trenching will be undertaken on some of the anomalies in order to gain a better understanding of the mineralization and mineralization controls causing the soil anomalies prior to drill testing. Permitting for an initial drilling campaign for the copper-gold anomalies at Coaxtlahuacan and Coaxtlahuacan Norte has commenced.

Geological Setting:
Violin 2 is underlain by metamorphic rocks believed to be of the Middle Jurassic age and belonging to the Xolapa Complex (metasediments and intercalated metavolcanics) and the Tecocoyunca Group (sediments). These are unconformably overlain by Cretaceous age limestones of the Morelos formation and hematite matrix breccias believed to be of the Chaolapa Formation. Tertiary age stocks ranging from quartz diorite to quartz monzonite composition have intruded these formations on the property.Mineralization:
There are at least 4 main styles of mineralization on the Violin 2 project area:- Copper-gold porphyry mineralization associated with quartz diorite and quartz monzonite stocks in the northwestern part of the property. There are two prominant soil anomalies in areas referred to as the Coaxtlahuacan and Coaxtlahuacan Norte. The nature of the intrusives assoicated with the mineralization and accessory magnetite suggests a mineralization model of porphyry copper - gold deposits with a strong similarities to iron oxide copper gold (IOCG's) end-members. The copper-gold anomaly on the Coaxtlahuacan and Coaxtlahuacan Norte grid and bedrock geology has very strong similarities to the setting of the Los Filos - El Bermejal gold mine of Goldcorp, located 68 kilometres to the northwest.
- Volcanogenic massive sulphide or "VMS" (Ag-Au-Pb-Cu-Zn) mineralization , such as at El Carrizal on the adjacent El Violin claim where drilling in the 1970's by INCO subsidiary "Draco" resulted in an historical resource estimate (non 43-101 compliant) of 7.5 million tonnes of 5.3% zinc, 0.70% lead and 34 grams/tonne silver. On the Violin 2 project area VMS mineralization is associated with what are believed to be metasediments and metavolcanics of the Middle Jurassic Xolapa Complex.
- Epithermal Ag-Au polymetallic vein deposits -- these high grade zones in some cases have been developed by local miners in the Mezcaltepec area. The occurrences in some instances are associated with quartz diorite sills, that intrude sediments of the Tecocoyunca Group. Silver-gold-Lead-zinc mineralization occurs as galena, sphalerite, stibnite and presumeably other sulphosalts in a barite-quartz gangue.
- Carbonate-hosted or carbonate replacement (CRD's) silver-lead-zinc deposits are hosted in limestone's and marbles of what is believed to be part of the Xolapa Complex. Strong silver-lead-zinc and gold soil anomalies are developed over some areas underlain by the limestones, have been subjected to karsting. It is speculated that silver-lead-zinc-gold bearing solutions have been deposited in some of the karst cavities during later deformation, possibly associated with intrusion of the quartz diorites in the area.
Exploration Work:
Alphamin has completed the first phase of geochemical soil sampling over the project area with over 10,000 samples having been collected from this program. In addition, geophysical (induced polarization and magnetic) surveys over the Coaxtlahuacan grid have been undertaken. Based on the results of the soil sampling, the sampled area has been divided into 4 zones, each of which has unique geochemical signatures indicative of the style of mineralization in the underlying bedrock. The areas are, from north to south: Coaxtlahuacan Norte, Coaxtlahuacan, Mezcaltepec, San Isidro and Piedra Iman. Initial follow-up prospecting and rock sampling has also been completed over the grids.At Coaxtlahuacan Norte an annular or donut-shaped copper-in-soils anomaly, defined by copper values greater than 210 ppm, is 720 by 820 metres in size (~50 hectares) and is open to the north and west.
