Mexican Gold Samples 5.11 g/t Gold & 7.15 % Zinc Over 2.0 Metres and 11.14 g/t Gold Over 1.4 Metres at Changarro Zone, Las Minas Project
TSX VENTURE: MEX
THUNDER BAY, Ontario, July 24, 2018 (GLOBE NEWSWIRE) -- Mexican Gold Corp. ("Mexican Gold" or the "Company") (TSX-V:MEX) (OTCQB:MEXGF) (FRA:4QW1) announces that continued sampling of historical mines and new discoveries at the Changarro zone has yielded significant assay results including:
- 5.11 g/t gold, 7.15% zinc over 2.0 metres from outcrop 7.0 metres southwest of the Guadalupe 3 mine.
- 5.0 g/t gold over 2.0 metres at Guadalupe 3 mine.
- 11.14 g/t gold over 1.4 metres at Las Escondida mine.
- 4.06 g/t gold, 32.00 g/t silver, 0.72 % copper over 1.0 metres at Changarro mine.
- 4.85 g/t gold, 12.70 g/t silver over 0.80 metres at small mine below Changarro.
See Table 1 below for selected sample results.
The 2018 fieldwork has focussed on two extensive mineralized zones of historical mining importance: gold-bearing quartz vein deposits at Pueblo Nuevo and the gold skarns of Changarro. The Changarro – La Perdida area is an historical skarn mining zone extending more than 400 metres by 850 metres on surface. The zone is exposed on the canyon walls between 280 and 600 metres above and to the east of the Las Minas 43-101 resource skarn deposits– see Figure 1 Plan View of Las Minas Area. Gold occurs in both high-temperature, proximal skarn (garnet–magnetite-sulphides) related to dike contacts and structurally-controlled, low-temperature distal skarn (jasperoid-magnetite-tremolite-wollastonite +/- sulphides).

Changarro – La Perdida Area Exploration
The Changarro – La Perdida area has caught the attention of several previous operators due to the high density and the scale of historical mining activity. Previous work was limited to sampling surface showings and underground in mines, along with localized drilling from 2 drill set-ups. The complex structural picture which controls the widespread mineralization in the area is only now being investigated through stripping and trenching of the extensive, thin overburden cover.
As detailed in an earlier press release (May 1, 2018) multiple lost historical mines and workings have been discovered along with many new mineralized showings during the ongoing fieldwork.

Recent stripping undertaken since the latest assay results has exposed diorite dikes related to the contact-proximal type skarn mineralization at two historical mines: Llanillo 1 and La Lola – see Figure 3 - Overburden Stripping at La Lola Mine. The dikes, clearly co-magmatic to the main Las Minas sill, show a strike direction of 140°, which is the same strike as the virtually identical diorite dike which hosts the high-grade El Dorado Dike Contact Zone 300 metres to the SW and 250 to 400 metres lower in elevation. This is also the orientation of several major regional structures. The high-grade El Dorado Dike Contact zone extends for over 330 metres along strike with drill intercepts grading up to 10.19 g/t Au Eq (4.15 g/t Au, 16.17 g/t Ag and 3.33 % Cu) over 38.0 metres – see press release March 1, 2018.
Additionally, work at the La Perdida Mine area located 850 metres to the ENE of Llanillo 1 has outlined a dominant structural direction of 120 degrees controlling the mostly distal type skarn mineralization over a width of more than 200 metres. This aligns with a significant observed local structure and may represent a flexure in the main structural direction.

Brian Robertson, President & CEO, stated, “Our ongoing field exploration work continues to deliver high-grade assays from historical mines and well as new discoveries within the Changarro – La Perdida area. These results from several widely-spaced localities clearly demonstrate that the high–grade mineralization is extensive and appears to be structurally controlled similar to the El Dorado Dike Contact zone.”

About Las Minas
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.
The district is host to a large gold, silver and copper skarn system that has a production history that extends back to the Aztec era. The Las Minas diorite intrusive measures approximately 10 kilometres in diameter and underlies the Las Minas concessions. The mineralization controls and association with magnetite appear to be similar to the Guerrero Gold belt, which is the site of the Los Filos and Morelos gold deposits.
