  • Of the top ten silver intersects released on the second week of March, five were from companies working in Mexico, according to Miner Deck. Vizsla Silver was first with 9.45 m @ 1,559 gpt Ag at Panuco, in Sinaloa, whilst Magna Gold was second with 55.95 m @ 156 gpt Ag at Margarita, in Chihuahua. Prime Mining, Capitan Mining and Avino Silver were also in the list, with their project in Sinaloa and Durango.


  • Rockland Resources Ltd. announced exploration is to initiate at its Elektra project in Sonora. The company is to review the surface and drill information generated in 2017, when 1,762 m were drilled in 16 holes. Best intercepts of that campaign include 33 m @ 1,058 ppm Li and 24 m @ 1,050 ppm Li. The target is a lithium in clays deposit akin to the nearby “Sonora Lithium” property owned by Bacanora Lithium PLC.
  • Orla Mining Ltd. is to begin exploration in and around its Camino Rojo mine in Zacatecas. The company is planning to invest $10 M in exploration in Mexico during 2022. The current year drilling program is to infill drill the deposit and reduce the spacing to 50-125m  in the sulfide zone. Last year program returned up to 108 m @ 2.38 gpt Au; 111 m @ 2.63 gpt Au; 58.5 m @ 2.51 gpt Au; 115.5 m @ 2.11 gpt Au; 64.6 m @ 3.04 gpt Au; 55.5 m @ 4.47 gpt Au; 55.5 m @ 4.95 gpt Au. The 2021 regional exploration program included an airborne magnetic survey, an IP survey, soil sampling and direct exploration under cover with 9,146 m of RAB drilling on 284 holes (holes 500 m apart, with 1,000 m line spacing) to sample the bedrock under shallow cover (up to 3 m @ 1.94 gpt Au, 7 km from Camino Rojo). That effort produced several targets that are to be followed-up this year, while target generation still continues.
  • Infinitum Copper Corp. announced the discovery of new zones of high-grade copper mineralization on the surface at its Adelita project in Sonora-Sinaloa. Mapping, prospecting and sampling (1,024 channel samples) program identified the Cerro Grande Footwall, Las Trancas and Pericos zones. At Cerro Grande, sampling on a garnet skarn alteration zone returned 7.50 m @ 1.88% Cu, 0.89 gpt Au, 127 gpt Ag, 0.9% Zn. Skarn hosted mineralization is also present at Pericos, estimated at 12 m in width, with results pending. At Las Trancas an oxidized breccia returned 0.5 m @ 3.67% Cu, 1.14 gpt Au, 4.2% Zn, with the structure having been traced for 780 m, and pending results in trench samples. A 14.8 line-km magneto-telluric geophysical survey is to be conducted over the Cerro Grande, Cerro Grande Footwall, Pericos and Las Trancas zones. Drilling is to start in late March.

At Bolivar, 13,072 m of drilling were completed, as well as 21,059 m of infill drilling and 4,703 m of brownfield drilling at Cusi. The company held cash and cash equivalents of $34.9 M by the end of the year. “In Q4 2021, the Company announced its increased focus on copper and other steel-making products, including the strategic review process for the silver-producing Cusi Mine in Mexico. As part of this process, the carrying value of Cusi was reviewed. As a result, a non-cash impairment charge of $35 million was recognized for the year”.
  • Americas Gold and Silver Corp. reported consolidated financial and operational results for the year 2021. At Cosalá, in Sinaloa, re-started operations in September after a long struggle with an illegal blockade “after reaching an agreement with union representatives and certain Mexican government ministries in July 2021…. Production from the San Rafael mine increased during Q4‐2021 as the normal mining cycle was re‐established.  The Los Braceros processing plant was fed with a combination of over 20,000 tonnes of existing stockpiled ore and new production from the mine.  The milling rate ramped up in tandem with mine production, averaging approximately 1,700 tonnes per day during December 2021 and continuing into 2022”. During the Q4 61 K Oz Ag, 4.2 M Lb Zn, 1.7 M Lb Pb were produced.
  • Orla Mining Ltd. announced results for the Q4 and year 2021. During its commissioning year, at Camino Rojo in Zacatecas, 2.06 M tonnes were mined, of which 1.71 M tonnes were processed, 349.4 K placed on the low grade stockpile and further 2.05 M tonnes of waste were moved. The stacked ore grade was 0.74 gpt Au, and the gold produced was 2,422 Oz. “Orla continues to evaluate multiple development scenarios on the Camino Rojo Sulphide Project. The development scenarios being considered to potentially form the basis of a Preliminary Economic Assessment (“PEA”) currently include: (1) an underground mining option, (2) an open pit mining option with processing at a to-be-constructed sulphide facility at Camino Rojo, and (3) an open pit mining option with processing at Newmont’s Peñasquito plant. Based on the additional drilling and testwork to date, all development options remain possible”.
