Mamatla
Impact holds a 100% interest in the 200km2 Mamatla Mining District located immediately southwest of and adjacent to IMPACT's Royal Mines of Zacualpan Silver Project and production facilities in central Mexico. This acquisition increases IMPACT's mineral concession holdings in the region by 160% to a total of 325km2. The Mamatla Project is host to both epithermal vein systems and volcanogenic massive sulphide (VMS) deposits. IMPACT's initial interest lies within the silver and gold epithermal vein systems which were not the primary focus of past exploration work.
Among the 70 mineral prospects known on the Mamatla concession, the most significant identified to date are the Aurora I and the nearby Capire Prospects. In the auction bid document publicly released by the Mexican Geological Survey, the Aurora deposit is described with an indicated resource of 194,000 tonnes grading 1.28g/t gold, 180g/t silver, 2.13% lead and 4.45% zinc. The Capire deposit is described with an indicated resource of 1,154,500 tonnes grading 0.22g/t gold, 73g/t silver, 0.45% lead and 1.13% zinc in a near surface zone with potential for open pit mining and open for expansion. Several past drill highlights, 2,218g/t silver and 3.65g/t gold over 6m, indicate that there are also higher grade portions to this deposit. Over 60 targets remain untested by drilling.
IMPACT has not independently verified these resource estimates and they are not compliant with NI 43-101 requirements, therefore they should not be relied upon. IMPACT has also not verified the results of the previous exploration work quoted from news releases of Valerie Gold Resources. IMPACT believes the historical resource estimates and results provide an indication of the potential of the Mamatla Project, and are clearly relevant to IMPACT's decision to purchase the project and to IMPACT's plans for further exploration work.
HUATECOSCO PROSPECT
IMPACT crews found two old mine workings at the historic Huatecosco Prospect located about 10 km southwest of the Royal Mines of Zacualpan processing plant. Grab samples from the mine dump of the lower workings returned assays of 409 g/t silver, 5.41 g/t gold, 0.9% zinc and 0.5% lead. Crews were able to enter the upper inclined shaft which leads to a small underground working on the vein in oxidized material. Sampling of exposed oxidized material in the upper workings vein returned 1.88 g/t gold and 40 g/t silver over 8.7m. The vein was also accessible in another area where samples returned highly variable assay results with grades up to 189 g/t gold over 1.5 m. IMPACT geologists believe that this is a wide vein containing variable, locally very high gold grades in the near surface oxidized zone and more consistent silver and gold rich grades at depth. IMPACT plans to reopen the lower workings and sample the vein at a lower level in preparation for future drilling.
SARA MAMATLA PROSPECT
The Sara Mamatla Prospect is located 2.5 km northeast of Huatecosco. A grab sample of vein material from the mine dump assayed 380 g/t silver, 1.14 g/t gold, 1.0% zinc and 1.9% lead. Plans are to reopen the old mine for crews to sample the vein in-situ.
SAN JOAQUIN PROSPECT
The San Joaquin Prospect is located 2.5 km west of Huatecosco. A grab sample of vein material from the mine dump assayed 295 g/t silver and 1.5% zinc. Plans are to map and sample this area and if possible establish access to old mine workings.
ZAPOTE PROSPECT
A series of altered andesite dikes are exposed along a road 4 km west of Huatecosco. IMPACT crews sampled two of these dikes, which returned assays of 14.90 g/t gold across 0.5 m and 7.29 g/t gold across 0.6 m. Nearby there is a 20 m wide vein that returned low grade values on the roadcut, but may have potential for mineralization at depth. IMPACT plans to carry out a program of mapping, trenching and sampling in this area to better understand the mineralizing system and its potential.
IMPACT management is pleased that the initial reconnaissance of the northeastern part of the new Mamatla concession turned up many prospects with significant assay results.
