Mexican Gold Mining Corp. (TSX-V: MEX) is pleased to announce the final assay results from the 2020 drilling program in which a total of 65 holes were drilled for 10,221m. All of the drilling reported in this news release targeted potential extensions of several zones in the El Dorado resource area.

“These results mark the successful conclusion of our 2020 drill program which was designed to expand and upgrade resources at the El Dorado resource zone. Drilling demonstrated that the deposit remains open in several directions and significantly expanded tonnage. This drilling will form the basis for an updated resource model and a Preliminary Economic Assessment at Las Minas,” stated Philip O’Neill, Chief Executive Officer.

Holes LM-20-ED-74, LM-20-ED-80, LM-20-LB-03, and LM-20-LB-04 returned no significant assays.
The AuEq grade is calculated using the following formula:
g AuEq/t = g Au/t + (0.0123077 x g Ag/t) + (1.4492753 x %Cu)
This formula is based on prices of US$1,300.00 per ounce gold, US$16.00 per ounce silver, and US$2.75 per pound copper. Metal recoveries were not included in the equivalency calculation since the metallurgical studies completed to date indicate a recovery of 89 per cent for gold, 84 per cent for silver and 95 per cent for copper.
West Dike Contact Zone Drilling:
The WDC zone consists of mineralization within 2 sub-parallel structures related to steeply-dipping diorite-marble contacts and the thickened, enriched ore shoots formed where the dike contacts meet the flat-lying El Dorado zone sill contact. Each has a distinct mineralization style. The WDC zone ore shoot is the richest portion of the Las Minas resource, so the recent expansion of this zone is significant. The southern half of the vertical portion of the WDC zone, now defined by multiple intersections, was essentially theoretical until recent drilling.
Holes LM-20-ED-76 (21m of 9.82 g/t AuEq) and LM-20-ED-81 (12m of 4.31 g/t and 8m of 3.34 g/t AuEq) successfully infilled the 100m by 75m expansion of the WDC-ED Zone ore shoot created by recent drilling. These holes also intersected the upper WDC zones above and below these ore shoot intersections.
Drilling on the southern limbs of the WDC vertical zone has and defined an up-dip height of 135 to 170m over 150m of strike:
LM-20-ED-75 cut a composite mineralized zone including 15m of 2.76 g/t AuEq, which has extended the zone 100m to the south.
LM-20-ED-72 (18m of 3.38 g/t AuEq) cut the WDC Zone 135m up-dip from the ED zone top and 215m up-dip from the lowest WDC zone intersection in the area. The true width of the zone here is uncertain (likely 6 to 8m) as the hole was drilled steeply to the zone orientation.
LM-20-ED-81 was also drilled steeply to the zone due to terrain constraints. A nearly continuous 135m of mineralization was encountered which included multiple intersections of the upper and lower WDC Zones and the ED Zone. The true widths of these intersections cannot be established but may be inferred from surrounding intersections which were oblique to the zone.
East Dike Contact Zone Definition and Expansion:
The EDC has similar morphology to the WDC, with lesser thicknesses and grades, but it had not been included in previous resource modelling due to sparse drilling. Multiple mineralized intercepts in the 2020 program define continuous mineralization, which remains open to the SE.
LM-20-ED-73 intersected 28.3m of 2.03g/t AuEq closely above the EDC-ED Zone ore shoot. This is an 80m extension from the closest EDC zone intercept in hole LM-20-ED-59 and a 150m extension of the ore shoot to the south-east from hole LM-20-ED-57.
West El Dorado Zone Expansion:
Drilling detailed in the previous news releases of 2020 had appended a 450m long strip 90 to 135 m wide to the ED zone. The latest holes focussed on continuing this expansion to the north.
LM-20-JB-41 (7.8m of 1.85 g/t AuEq) and LM-20-JB-46 (4m of 4.50 g/t AuEq) represent 160m and 140m west extensions to the ED zone 100m and 150m north of pre-2020 drilling. LM-20-JB-42 (9m of 2.43 g/t AuEq) successfully infilled the 160m extension of hole LM-20-JB-41.
WDC Zone North Extension:
The EDC Zone extends as far north as the ED Zone but weakens in its northern reaches. Holes LM-20-JB-44 (14m of 2.52 g/t AuEq) and LM-20-JB-45 (10m of 1.52 g/t AuEq) extended the WDC zone a total of 180m to the NW, to complement the ED zone expansion in this area.
