  • No relevant News.


  • Aztec Minerals Corp. received sampling results and completed its phase 1 surface exploration program at Cervantes, in Sonora. Detailed geological mapping and continued chip channel sampling of exposed road cuts were carried out. The “surface road cut sampling and detailed geologic mapping has verified the strong relationships found between the quartz feldspar porphyritic intrusive, phyllic alteration and gold mineralization… Quartz veinlet intensity mapping shows strong correlation to the drill hole gold grade-thickness”. The phase 2 exploration program comprises a reverse circulation drilling campaign to expand the California target in all directions. To date Aztec has competed over 10,500 m of drilling on 54 holes at the Cervantes project.
  • Silver Dollar Resources Inc. provided a progress report on the Nora project in Durango. Silver Dollar received all historical technical information from Canasil and is “organizing it into a database to analyze, interpret and then plan the next phase”. There are 13 diamond holes from Canasil’s 2020-2021 drilling campaign with a total of 3,296 m testing 500 m of the Candy structure, returning up to 3.29 m @ 6.44 gpt Au, 884 gpt Ag and 1.53 m @ 20.59 gpt Au, 1,290 gpt Ag.
  • Infinitum Copper Corp. commenced drilling at its 6,450 ha La Adelita property in Sonora. The 2,500 m diamond drilling program with 15 holes is designed to expand the high-grade mineralized area at the Cerro Grande zone and to test for mineralization at depth at Las Trancas zone. Drilling is aimed to extend the north-south extent of mineralization to 500 m and step out up to 700 m west of the known mineralization. At Las Trancas, 5 Km from Cerro Grande, the Sangre de Toro feature is to be tested with the first drilling in the area for the presence of a large mineralized structure.
  • Vortex Metals Inc. initiated surface geological work at its 12,041 ha Riqueza Marina project in Oaxaca. As the Santa Cruz Tagolaba community granted approval, Vortex can now commence work, including trenching, over an area including the Rhyolite Dome target, where substantial size and coincident gravity and magnetic anomalies along with anomalous copper values are interpreted to reflect a concealed sulfide deposit.


  • Impact Silver Corp. announced its financial and operating results for Q1 2023. At its Royal Mines of Zacualpan mine operations, in Estado de Mexico, 38.7 K tonnes were milled during the period, averaging 162 gpt Ag, to produce 167 K Oz Ag. Reported revenue was $5.1 M, mine operating earning $0.6 M and the net loss $0.6 M, with a working capital of $15.7 M and a cash position of $14.3 M by the end of the period.
  • Guanajuato Silver Company Ltd. announced financial and operating results for Q1 2023. During the period the company produced 458.8 K Oz Ag, 4,413 Oz Au, 0.91 M Lb Pb, 1.15 M Lb Zn (or 938 K Oz AgEq) at El Cubo Mines Complex, Valenciana Mines Complex and San Ignacio mine, in Guanajuato, and Topia mine, in Durango. Revenue was US$17.1 M, with a net loss of US$8.7 M. The All-in sustaining cost (AISC) was $21.83 per AgEq. Infrastructure upgrades to deliver improvement in 2023 include Falcon concentrators at El Cubo and Valenciana, the rehabilitation of the Cata Shaft already completed and the implementation of hydraulic backfilling of tailings at Valenciana.


  • Silver Viper Minerals Corp. granted 5.15 M incentive stock options to directors, officers and consultants to purchase up to 5.15 M common shares in the capital of Silver Viper. (La Virginia, Sonora).


  • Avino Silver & Gold Mines Ltd. released the results of ten drill holes from below Level 17, the current deepest workings of the Avino mine in Durango.

Highlighted true width intercepts comprise 2.61 m @ 0.06 gpt Au, 75 gpt Ag, 2.58% Cu; 19.90 m @ 0.02 gpt Au, 30 gpt Ag, 1.29% Cu; 3.00 m @ 0.99 gpt Au, 34 gpt Ag, 0.08% Cu; 35.73 m @ 0.14 gpt Au, 28 gpt Ag, 0.65% Cu; 48.40 m @ 0.08 gpt Au, 45 gpt Ag, 0.55% Cu; 36.00 m @ 0.16 gpt Au, 27 gpt Ag, 0.81% Cu; 1.30 m @ 0.05 gpt Au, 97 gpt Ag, 2.28% Cu. “The changing tenor of the mineralization could be reflecting a transition from epithermal to porphyry-style mineralization”.
  • Heliostar Metals Ltd. reported its first drill results from the Ana Paula project in Guerrero. The first two holes drilled by Heliostar targeted the “High Grade Panel” at the core of Ana Paula. Highlighted core length intervals comprise 118.55 m @ 5.44 gpt Au (including 44.5 m @ 11.0 gpt Au, which include 4.0 m @ 48.5 gpt Au); 101.12 m @ 8.35 gpt Au (including 53.2 m @ 11.0 gpt Au). “the High Grade Panel is approximately 250 metres long by 100 metres high by 60 metres thick… hosted primarily in a polymictic breccia unit, although it extends outward into the surrounding granodiorite and limestone. Gold mineralization is directly associated with the proportion of sulphide minerals in the rock”. Heliostar is re-evaluating the project as a high-grade underground mine.
  • Capitan Mining Inc. provided an exploration update on its Cruz de Plata project in Durango. New interpretation points to the Jesus Maria vein to have a potential strike length of 2.8 km, the Santa Teresa vein of 1.8 km and the San Rafael North vein of 1.3 km before going under cover.

Mexico’s Best Drilling Intercepts, Fourth Week of May 2023

Five companies released drilling assays from projects in Mexico during the week. The most impressive results are the gold intercepts by Heliostar Metals at the Ana Paula project in Guerrero. The company reported results from holes aiming to better define the high-grade core of the deposit, which will aid in the planning of an underground mine. The deposit sits at the northern end of the Guerrero Gold Belt, and is one of those beasts hard to put in a cage, as it presents several mineralization styles. The Morelos platform sediments are intruded by a plagioclase-biotite porphyry that produced local hornfelsification and skarnification of the sedimentary rocks. Pyrite, marcasite and arsenopyrite are present as veinlets, stockworks and disseminations in these altered rocks, in breccias, and as narrow semi-massive sulfide replacements at intrusive contacts. A late low sulfidation epithermal veining stage with visible gold is also present in the deposit.

Discovery Silver’s Cordero project in Chihuaha is also one of these deposits not easily cajoled to only a mineralization style, with high grade intermediate sulfidation epithermal veins cutting through (overprinting?) disseminated Ag-Pb-Zn mineralization (earlier?) related to the intrusion of felsic laccoliths, dikes and sills into a calcareous sedimentary sequence, with skarn and carbonate replacement mineralization dominating parts of the deposit. A very broad classification would put Cordero as polymetallic intrusive related mineralization.

Prime Mining’s Los Reyes project and GR Silver Mining’s Plomosas property, both in Sinaloa, are intermediate sulfidation epithermal systems with a strong structural component. Avino Silver & Gold’s is finding stronger copper grades 800 m below the surface on the Avino vein, and is considering the probable presence of a porphyry copper setting at depth.
