Mexico’s Best Drilling Intercepts, Third Week of January 2023

Four companies released drilling results during the third week of January 2023 in Mexico. All the results come from epithermal systems developed along strong structures, three of which are measured, at least locally, in the tens of meters in width. Almadex’s San Pedro project in Jalisco shows evidence of intermediate and high sulfidation epithermal activity. GoGold’s Los Ricos North is in a district that shows mineralization probably straddling low to intermediate sulfidation mineralization. Both GR Silver’s San Marcial (part of the regional Plomosas project) in Sinaloa and Capitan Mining’s Cruz de Plata in Durango drilling results are part of intermediate sulfidation epithermal systems.

  • The Ministry of the Environment and Natural Resources (SEMARNAT) withdrew the permit to Fortuna Silver Mines, which operates the San Jose mine in Oaxaca through the company Minera Cuzcatlán since, according to SEMARNAT, it incurred in several irregularities. Such permit had been previously granted by some servants of SEMARNAT. In 2022, SEMARNAT said that it had been a misspelling to have issued a permit for 12 more years for the operation of this company. SEMARNAT was even questioned for providing legal advice to the company in order to obtain the environmental impact authorization and the regularization of construction of works for which it did not have authorization. With the suspension of the permit, SEMARNAT said that the company can appeal and resort to its influence peddling as it has done since its settlement in Oaxaca. However, if the judges confirm the resolution, it must withdraw and return the land to its owners, in addition to repairing the damage caused by the excessive pollution it has generated in the area.
  • Compañia Minera Cuzcatlán (Fortuna Silver) responded to SEMARNAT that it is operating normally at its San Jose mine in Oaxaca under complete legality. Derived from the notification received by the Ministry of the Environment and Natural Resources (SEMARNAT) at the beginning of 2023, regarding the intention of evaluating the MIA (Environmental Impact Statement) granted legally and correctly in December 2021, it is notified that this new procedure does not affect the daily activities of the Company, thus confirming that the San José Mining Unit, located in San José del Progreso, Oaxaca, is operating normally. Fortuna Silver Mines, communicated on January 5 of this year, that its San José Mining Unit, which operates through its subsidiary Compañía Minera Cuzcatlán, fully complies with all current environmental laws, for which it has expressed its disagreement and is taking legal measures to protect its more than 1,200 employees, a value chain made up of more than 600 companies, 150 of them from the area, as well as an annual income of more than MXP $600M that benefits more than 30,000 people in the Central Valleys of Oaxaca.  “Likewise, the Company highlights that, in 11 years of operation, it has been inspected 15 times by the Federal Attorney for Environmental Protection (PROFEPA), in turn it has registered two inspections by the National Water Commission (CONAGUA), who in none of their proceedings have ruled on facts and/or indications of contamination at the site or derived from the operation of the San José Mine. Finally, Compañía Minera Cuzcatlán reiterates its commitment to continue working together with neighboring communities to improve and expand the social benefits of its operation, through sustainable development initiatives”.

ON MEXICO ISSUE

  • Trafigura Pte Ltd., announced that along with eFactor Network and a number of financial institutions are piloting a Sustainable Supply Chain Finance Program for mining companies in Mexico.  The Program, the first of its type and providing a model that can be scaled across the region, is structured to improve mining companies’ working capital whilst driving responsible sourcing practices along the metals value chain.
  • GR Silver Mining Ltd., Vizsla Silver Corp., Mammoth Resources Corp., GoGold Resources Inc., and Almadex Minerals Ltd., reported the best drilling intercepts in Mexico on the third week of December, 2022. Details are shown in the table below:

ON EXPLORATION

  • Aztec Minerals Corp., released final results from its 2021-2022 drilling program at its Cervantes project. The 2022-2022 drilling program consisted of 27 RC totaling 5,249m, and 11 oriented core totaling 2,558.5m for a total combined amount drilled of 7,837.5m in 37 drill holes on the California Zone, California Norte, Jasper, and Purisima Este targets. It was successful in intercepting strong mineralization, as well as in expanding the targets.  “The multi-element ICP values support the exploration model of the California zone being at the highest portion of a porphyry system, where an overlying high sulfidation zone has been eroded away”. Results of this drilling program are currently being analyzed in order to refine future targeting.
  • Minaurum Gold Inc., provided an updated on its Adelita project in Sonora, which is under an option agreement with Infinitum Copper Corp. Infinitum has identified five main target areas of which Cerro Grande is being drilled and plans to drill Las Trancas target soon. Significant mineralization has been intersected at Cerro Grande target in hole AD-22-0018 with 1.91% Cu, 2 g/t Au, and 41 g/t Ag over a true width (TW) of 20.6m; and hole AD-22-0019 with 1.01% Cu, 0.52 g/t Au, and 40 g/t Ag over a TW of 32.25m, including 1.68% Cu, 0.83 g/t Au, and 59 g/t Ag over a TW of 17.05m. Cerro Grand Target is a mineralized zone of up to 36m thick, over 250m deep and has a strike 200m.
  • Mammoth Resources Corp., presented results from six holes for a total of 620.7m from its 27 holes diamond drilling program at its Tenoriba project in Chihuahua. Highlights of the drilling include hole TEN21-22 collared on Carneritos Zone with 0.98 g/t Au and 10 g/t Ag (1.12 g/t AuEq) over 3m, and 0.57 g/t Au and 8 g/t Ag (0.68 g/t AuEq) over 10.5m; and hole TEN21 -24 with 1.14 g/t Au and 75 g/t Ag (1.13 g/t AuEq) over 39m, including 5.28 g/t Au and 13 g/t Ag (5.45 g/t AuEq) over 3m, including 1.45 g/t Au and 11 g/t Ag (1.60 g/t AuEq) over 9m, plus 0.46 g/t Au and 2 g/t Ag (0.48 g/t AuEq) over 42m, including 1.21 g/t Au and 5 g/t Ag (1.28 g/t AuEq) over 12m.  These six holes bring the total meters drilled in the recent phase to 3,244.25m in twenty seven holes.
  • Southern Empire Resources Corp., has initiated the field exploration program work on its recently optioned Centauro property. The company contracted PhotoSat Information Ltd  to provide maps of alteration mineral suites typically associated with epithermal precious metal deposits, using their proprietary processing methods for16 band WorldView-3 and high-resolution ASTER satellite optical spectral data. Results of the PhotoSat studies show significant trends highlighting argillic, sericite, and chlorite alteration. Southern also collected 396 soil samples  at 50m spacing along E-W lines, spaced 100-200m apart to cover a zone of prospective alteration and mineralization over 4km strike length. Assays are pending.
  • Monumental Minerals Corp., completed reconnaissance exploration program, which consisted of detailed geological mapping, regional stream sediment sampling, ground radiometric geophysical surveys, and lithogeochemical sampling to delineate discreet drill targets at its Jemi Rare Earth Element project. To date, 37 whole-rock analytic results from rocks collected at the Jemi project of which 11 have returned values greater than 0.15% total Rare Earth Oxide (TREO), including six samples that returned values greater than 0.23% TREO and up to 0.43% TREO. Results for 269 samples are still pending to arrive. Heavy rare earth oxide (HREO) values (include dysprosium (Dy) and terbium (Tb)), ranged between 1614 ppm and 39 ppm in peralkaline pegmatites, averaging 447 ppm. Six samples exceeded 680 ppm, including three that exceeded 830 ppm. Light rare earth oxides (LREO) values including neodymium (Nd) and praseodymium (Pr), returned values up to 0.26% and 0.23%, with values in trend with HREO concentrations suggesting similar REE-hosting phases in the peralkaline rock samples. “Geological mapping has confirmed that samples with the highest TREO and HREO values are from pegmatitic bodies. Three-dimensional airborne magnetics modeling show that surface pegmatite bodies are spatially associated with a numerous larger magnetic anomalies at depth that may represent potential source intrusions. Specific drill locations will target these pegmatites”.
  • Almadex Minerals Ltd., released results from the second hole drilled in 2022 at its San Pedro project in Jalisco.  Hole SP-22-004 intersected 846 /t Au over 1.3m. The current drilling program intends to better understand the orientation and distribution of the breccia zone so that further, more focused drilling can eventually be carried out.
  • Minaurum Gold Inc., provided an updated on its Taviche project in Oaxaca, which is under an option agreement with Fortuna Silver Corp. Fortuna is currently focused on the re-negotiation of surface rights to be followed by drill permits. “Review of historic data and field mapping over the last year identified the possible continuation of the Mezcal Fault for 3km to the northwest.  Drill targeting is in progress along the Mezcal Fault to test for both Mezcal-style gold mineralization and silver bonanza style mineralization associated with jasperoid-related mantos”.  Another goal is to develop additional concepts to test the potential at depth at the Cerro La  Mina Zone where a drill hole encountered 235 g/t Ag and 0.19 g/t Au over 46.3m.

Mexico’s Best Drilling Intercepts on the Third Week of December 2022

This past week five companies posted new results from drilling at its projects in Mexico. GR Silver’s Plomosas project in Sinaloa presents relevant intercepts in gold, silver, lead and zinc. Vizsla’s Silver Panuco project, also in Sinaloa, presents significant gold and silver drill intervals, both deposits displaying clear epithermal intermediate sulfidation systems. Los Ricos North project in Jalisco presents gold and silver rich intervals, with mineralization being regarded as part of a low sulfidation system by GoGold Resources, but probably also involving intermediate sulfidation mineralization.

Almadex Minerals posted good silver results from a second hole from the same drill pad as last week’s press release, with mineralization characteristic of epithermal intermediate sulfidation mineralization. In Chihuahua, the results released by Mammoth Resources from drilling high sulfidation mineralization at its Tenoriba project show good gold grades, highlighting the 39 m @ 1.14 gpt Au interval.

A total of 14 grab and chip samples collected on this trend averaged 0.6 g/t Au and 180 g/t Ag.
  • Monumental Minerals Corp., provided an update of its currently on-going exploration program at its Jemi project in Coahuila, which consists of detailed geological mapping, regional stream sediment sampling, ground radiometric geophysical surveys, and litho geochemistry. To date, the stream sediment sampling program, consisting of 47 samples has been completed. It returned 5 samples with values greater than 7.8 ppm dysprosium (Dy), 65.3 ppm neodymium (Nd); and up to 14.1 ppm Dy and 160 ppm Nd, defining four general areas of interest along the west and south portions of the company’s concessions, of which two are associated with known HREE mineralized (eudialyte bearing) peralkaline rock (Jemi Dyke Area and Veladora North). The remaining two areas with anomalous Dy and Nd concentrations were previously unrecognized as being prospective (Zone 2 and Zone 4). Follow-up exploration work to identify the source of the high REEs at these two areas will be undertaken during the current field program for quick delineation.

ON MINING

  • Capstone Copper Corp., reported Q3, 2022 production and financial results from its Cozamine mine in Zacatecas. The company mined 3,829 tonnes per day with an average grade of 1.86% and metallurgical recovery of 96.8%, to produce 36.74 M Lb Cu at a cash cost of USD $1.20 per Lb produced.

ON FINANCING

Mexico’s Best Drilling Intercepts, First Week of November 2022

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.

An additional $9 M is budgeted for 28,500 m of drilling across the broader land package and further $5 M for ore control and definition drilling in the ELG open pit and underground. “The ELG mining complex…. is hosted in the Mesozoic carbonate-rich Morelos Platform, which has been intruded by Paleocene granodiorite stocks, sills, and dikes. Skarn-hosted gold mineralization is developed along the contacts of the intrusive rocks and the enclosing carbonate-rich sedimentary rocks…. The style of mineralization at Sub-Sill South is like Sub-Sill and ELD, and is characterized by gold, which is strongly associated with bismuth and variable amounts of silver and copper. Gold occurs in variably sulfidized, pyrrhotite-rich skarn, while silver and copper mineralization is controlled primarily by the degree of sulfidation of the host skarn. Mineralization is associated with retrograde alteration characterized by the occurrence of phlogopite, amphibole, chlorite, calcite and lesser amounts of quartz and epidote, and local magnetite”.
