Mexican Gold Mining Begins Fieldwork at Las Minas Project

Mexican Gold Mining Corp., a Canada-based mineral exploration and development company, reports that fieldwork towards concluding an environmental baseline study has been initiated at the Las Minas project. Drilling operations at the Las Minas project have been planned to begin in early July 2020.

  • Mexican Gold Mining has hired Consultoría y Tecnología Ambiental (CTA), situated in Zacatecas, Mexico, to initiate an environmental baseline analysis at the Las Minas project for inclusion in the preliminary economic assessment study (PEA) of Mexican Gold Mining.
  • Mexican Gold Mining has also engaged Kluane Drilling (KDL) to begin a +3,000-m-drill program at the Las Minas project in early July 2020.

The commencement of the environmental baseline study at Las Minas, as well as drilling, marks the re-start of our much anticipated 2020 program. With the start of resource expansion and exploration drilling in early July, we will be well on our way towards achieving a PEA at Las Minas.

Philip O’Neill, Chief Executive Officer, Mexican Gold Mining Corp.

Drilling Program

A +3000-m-drill program will be initiated by Mexican Gold Mining to widen and upgrade the present resource located at El Dorado, which remains exposed in numerous directions.

In addition, a detailed drill program will follow up the discovery made at Cinco Senores hole LM-19-CS-13 in November 2019. At a vertical depth of 114 m, a shallow-dipping quartz vein of 5.2 m was intersected that assayed 8.94 g/t gold, which also included 21.37 g/t gold across 2 m.

It has been estimated that the actual widths of the intersections is 85% of the down-hole lengths. Historic drilling conducted at Cinco Senores had focused on the El Dorado mineralized horizon, located at least 70 m above this intersection. The 2020 drilling operations will try to define the veining and intersect additional robust gold values.

A historic mine in the Changarro region yielded high-grade gold assays in early 2020. These assays had not been sampled for at least 100 years. Channel samples, which were spaced 3 m apart and averaging 0.65 m in width, yielded an average of 8.82 g/t gold along the whole 52-m drift.

Such robust results triggered exploration work in February-March 2020, which revealed numerous lost mine workings, all carrying analogous Fe-oxide skarn and polymetallic veining inside a robust, mineralized, linear structural zone. This provides the first clear drill target within the geologically intricate but convincing mining cluster at the Changarro area and will be analyzed in 2020.

Environmental Baseline Study

CTA has initiated an environmental baseline study of the resource region located at the Las Minas project for inclusion in the upcoming preliminary economic assessment study of Mexican Gold Mining. CTA will also analyze the flora and fauna and the quality of the surface water.

In the surface water study, samples will be collected from the neighboring creeks and rivers to investigate the concentrations of mercury and metals (both dissolved and total) as well as other inorganic parameters such as color, pH, chlorides, sulfates, dissolved oxygen, hardness, conductivity, and total suspended solids.

The flora and fauna study will involve observations along transects in the area of influence of the Las Minas project to detect species of birds, herpetofauna, and flora, including potential protected species from these three groups. Three biologists specialized in these three particular groups will perform the work.

In addition, the biologists will collect the water samples to analyze them at an accredited Canadian laboratory. Towards the end of the program, CTA will prepare and present an environmental baseline study report to Mexican Gold Mining Company.

Quality Assurance/Quality Control

Mr Sonny Bernales, a qualified person as defined by NI 43‑101 and a registered Professional Geoscientist in the Province of British Columbia, is responsible for the supervision and logistics of all exploration activities carried out by Mexican Gold Mining on the property.

Mexican Gold Mining has also implemented and currently conforms to a rigorous quality control/quality assurance program that involves integrating mineralized standards and blanks into the sample stream, around 1 for every 10 samples.

The mineralized standards and blanks were acquired from CDN Resource Laboratories Ltd. of Langley, British Columbia, Canada. Every sample bag has been properly sealed and stored in a safe, restricted storage location before it is delivered to the laboratory.

Samples are directly sent by Mexican Gold Mining or collected by the laboratory vehicle with a chain of sample/custody submittal signed and dated. Mexican Gold Mining ships its samples to SGS Mineral Services (ISO/IEC 17025) located at Durango, Mexico—an independent, accredited laboratory.
