This week’s best intercepts were to be dominated by the long good-grade gold-silver intercepts of GoGold Resources on the Eagle zone of the Los Ricos South project in Jalisco…… if not by the release by Pan american Silver of lengthy intercepts of zinc-lead-silver-copper at its La Colorada Skarn deposit in Zacatecas, which is steadily confirming the presence of a World Class Mineral Deposit. Los Ricos South and the Plomosas mine, in Sinaloa, projects represent both intermediate sulfidation epithermal systems in veins and stockwork zones, while La Colorada Skarn and Cerro Las Minitas intercepts represent skarn systems.
At Los Ricos South the best intercept comprises 110.60 m @ 1.64 gpt Au, 265 gpt Ag, including a high grade zone of 11.50 m @ 11.35 gpt Au, 2,198 gpt Ag, whilst at Plomosas, in Sinaloa, the best intercept comprised 36.50 m @ 1.00 gpt Au, 268 gpt Ag, similar grades but lesser thickness, although true width and not core length as the former. Some of the core intervals at La Colorada Skarn are high-grade in silver, like the 58.30 m @ 417 gpt Ag, although far from representative of the overall grade. At Cerro Las Minitas, in Durango, the best intercept silver intercept is 1.90 m @ 599 gpt Ag, interesting, but obscured by the shadow of La Colorada Skarn, Los Ricos South and Plomosas and Plomosas silver results.
Base metals best drilling intercepts are dominated by those from La Colorada Skarn (LCS), as even a tenth of its length at those grades in lead and zinc would be considered a good intercept. The best lead intercepts from LCS comprise 58.30 m @ 11.95% Pb and 92.95 m @ 7.01% Pb, those of Plomosas 11.40 m @ 9.20% Pb and 36.50 m @ 2.40% Pb; and 1.90 m @ 16.90% Zn at Cerro Las Minitas. For zinc the results are not that different, with 197.50 m @ 7.21% Zn, 194.45 m @ 4.26% Zn and 90.85 m @ 9.08% Zn at LCS, 16.90 m @ 4.80% Zn and 6.50 m @ 6.80% Zn at Plomosas and 1.90 m @ 10.20% Zn at Cerro Las Minitas. Copper intercepts made it to this list not by the grade, but for the length of the intercepts at LCS, with 194.45 m @ 0.21% Cu and 197.50 @ 0.09% Cu.
