MEXICAN GOLD INTERSECTS 32M OF 4.56 G/T AUEQ AND 10M OF 10.98 G/T AUEQ AT EL DORADO
Mexican Gold Mining Corp. has released further assay results from the 2020 drilling program. So far, 52 holes have been drilled for 8,075 metres. The vast majority of the drilling has been targeting various potential extension zones at the El Dorado resource, which remains open in several directions.
Highlights
- Hole LM-20-ED-69 intersected 32 m of 4.56 grams per tonne gold equivalent and 13 m of 6.39 g/t AuEq. This hole increased the width of the West Dike Contact (WDC) zone ore shoot by 150 per cent at the south end.
- Hole LM-20-ED-66 intersected 12 m of 4.86 g/t AuEq and 24 m of 2.48 g/t AuEq. This hole increased the width of the main WDC ore shoot by 100 per cent at the north end and connected the El Dorado (ED) lower zone to the WDC zone.
- Drilling on the upper WDC zone yielded 10 m of 10.98 g/t AuEq in hole LM-20-ED-71 and 4.5 m of 9.35 g/t AuEq (within 21.7 m of 2.88 g/t AuEq) in hole LM-20-ED-64, 55 m and 40 m above the ED zone.
- Hole LM-20-ED-73 (assays pending) has intersected the East Dike Contact (EDC) zone ore shoot 175 m to the southeast of the previous intersection.

"Drilling at El Dorado continues to expand tonnage, which is still open in several directions," stated Philip O'Neill, chief executive officer of Mexican Gold. "We believe that the drilling to date is likely to significantly increase tonnage in a future resource estimate while also providing the basis for a preliminary economic assessment."

Holes LM-20-JB-34, LM-20-JB-39, LM-20-LP-01, LM-20-LP-02, LM-20-LP-03, LM-20-LP-04, LM-20-LP-08, LM-20-LP-09, LM-20-CS-19, LM-20-CS-20, and LM-20-CS-21 returned no significant assays.
The AuEq grade is calculated using the following formula: g AuEq/t equals g Au/t plus (0.0123077 multiplied by g Ag/t) plus (1.4492753 multiplied by Cu percentage).
This formula is based on prices of $1,300 (U.S.) per ounce gold, $16 (U.S.) per ounce silver and $2.75 (U.S.) 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 (WDC) drilling
The dike contact (DC) zones at Las Minas consist of mineralization within structures related to subvertical diorite-marble contacts, and thickened, enriched ore shoots formed where the DC zones meets the flat-lying El Dorado zone. Each has a distinct mineralization style. The WDC zone ore shoot is notably the richest part of the Las Minas deposits and it was incorrectly thought to be fully defined previous to this drilling. The tabular, vertical portion of the WDC zone south of section 8025N was essentially theoretical, with very little drilling until Q3 to Q4 2020.
LM-20-ED-69 intersected 32 m of 4.56 g/t AuEq and 13 m of 6.39 g/t AuEq. This hole unexpectedly increased the width of the ED zone/southern WDC ore shoot by 150 per cent from 40 m to 100 m on cross section 7825N. Local geology suggests that this intersection may represent a newly discovered DC type zone and another ore shoot as well.
LM-20-ED-66 intersected 12 m of 4.86 g/t AuEq and 24 m of 2.48 g/t AuEq. This hole has increased the width of the southern WDC ore shoot by 100 per cent, from 22 m to 44 m on cross section 7900N, 75 m north of LM-20-ED-69. There is space to further increase the width on this section. Additionally, this hole now connects a single previous intersection (referred to as the ED lower zone) to the WDC zone, adding 20 to 45 m of depth to it.
Drilling on the southern limb of the WDC vertical zone has yielded 10 m of 10.98 g/t AuEq in hole LM-20-ED-71 and 4.5 m of 9.35 g/t AuEq (within 21.7 m of 2.88 g/t AuEq) in hole LM-20-ED-64. Along with several other intersections, these holes show that the southern WDC zone occupies structures detached from the main dike and continues south for at least 200 m. It has now been intersected consistently 55 m above and up to 90 m above the ED zone.
East Dike Contact zone (EDC)
The EDC has similar morphology to the WDC, with lesser thicknesses and grades. The EDC has so far not been included in resource modeling due to the lack of drilling until Q3 to Q4 2020. It has now become clear that there is a curved steepening to the plunge of the EDC ore shoot which caused a few misses and allowed for only one previous intersection (LM-17-ED-43).
LM-20-ED-70 cut the EDC above the ore shoot, intersecting 10.4 m of 2.22 g/t AuEq in the EDC and two m of 1.77 g/t AuEq in the east ED zone.
LM-20-ED-73 (assays pending) intersected closely above the ore shoot with a strong EDC and ED zone. This is 95 m southeast of LM-20-ED-70 and 175 m to the southeast of the closest ore shoot intersection in hole LM-20-ED-57.
West El Dorado (ED) zone expansion
The entire western side of the ED zone has been open for expansion, subject to overcoming terrain challenges. Drilling detailed in the news release of Sept. 15, 2020, had appended a 450 m long strip 90 to 135 m wide to the ED zone. Further drilling is upcoming.
LM-20-JB-36 (4.1 m of 2.69 g/t AuEq) has added a further 40 m to the west extension of the ED zone on section 7900N, bringing the total west extension in 2020 to 175 m.
South El Dorado (ED) zone
LM-20-ED-62, at six m of 2.23 g/t AuEq, has expanded the ED zone by 65 m to the southwest.
LM-20-ED-63, a further 70 m to the southwest from hole LM-20-ED-62, intersected an atypical gold-rich, copper-leached portion of the ED zone with two m of 5.07 g/t Au.
