Mexican Gold Corp.‘s [MEX-TSXV; MEXGF-OTCQB; 4QW1-FSE] field exploration program at Pueblo Nuevo, part of the La Minas Project 270 km east of Mexico City in Veracrus State, Mexico, continues to yield high-grade sampling results. Recent assays from sampling of newly discovered surface outcrops and historical mines include:
- 81.3 g/t gold + 91.1 g/t silver + 17.1% zinc over 0.20 metres
- 25.2 g/t gold + 165.8 g/t silver over 0.15 metres
- 29.5 g/t gold + 95.5 g/t silver + 8.5% zinc over 0.20 metres
The 2018 fieldwork has focused on two extensive mineralized zones of historical mining importance: gold-bearing quartz vein deposits at Pueblo Nuevo and the gold skarns of Changarro. With 26 workers and three geologists on site, the company has been making significant progress investigating these previously under-explored areas.
As detailed in earlier press releases (see press releases May 31, 2017, March 27, 2018, April 18, 2018) multiple lost historical mines and workings have been discovered along with many new veins and mineralized showings in a mineralized corridor extending up to 600 metres along strike and contained within a 400-metre-wide shear zone.
Brian Robertson, President & CEO, stated, “Our on-going field exploration work continues to deliver high-grade assays from historical mines as well as new discoveries within the Pueblo Nuevo mineralized corridor. These results from several high-grade veins clearly demonstrate the extent of the high-grade mineralization at Pueblo Nuevo.”
Multiple new vein occurrences have been discovered in the Pueblo Nuevo Valley structural corridor, located to the east and parallel to the La Miqueta structure. The area of the Valley carrying mineralized quartz veins now has a demonstrated width of at least 400 metres Several high-grade results from initial sampling, spread over more than 600 metres of strike length, will be investigated further. Results include 3.26 g/t gold, 651.82 g/t silver and 0.71% zinc over 0.40 metres at Espiritu as well as 29.47 g/t gold, 95.50 g/t silver and 8.52% zinc in Vein in Float above Ramos Vein. There were numerous other good assays. Refer to company press release for more assays.
A typical continuous quartz vein in the newly discovered Tamiagua South Mine was sampled at 3-metre intervals over 69 metres of its length. The vein averaged 0.51 metres in width and yielded an average of 5.97 g/t gold, 45.4 g/t silver and 1.85% zinc from 23 samples. Complete sample results for Tamiagua South are in the company’s press release. As part of ongoing work at Pueblo Nuevo, the vein will be uncovered south of the mined area to extend its sampled strike length.
In 2017, the company reported an initial mineral resource estimate of 304,000 gold equivalent ounces (Au Eq ozs) contained within 4,970,000 tonnes grading 1.90 g/t AuEq (0.92 g/t gold, 0.59% copper. 4.37 g/t silver) in the Measured and Indicated category for the Eldorado/Juan Bran and Santa Cruz zones, with an additional Inferred Resource of 719,000 AuEq oz contained within 10,304,000 tonnes grading 2.17 g/t AuEq. (1.08 g/t gold, 0.66 % copper, 3.99 g/t silver)
The Las Minas Project hosts near-surface gold, silver and copper skarn mineralization and high-grade gold – silver mesothermal vein deposits. The project is comprised of six mineral concessions covering approximately 1,616 hectares (3,995 acres), with several small scale, past-producing mines and a number of untested targets.
