ON MEXICO ISSUE
- The mining industry is one of the industries that consumes the least vital liquid and, at the same time, the one that acquires it at the highest cost, while agricultural use, which represents 77% of national water consumption, does not contribute any payment for it to the public treasury. Despite the fact that it only consumes 1.4% of the country`s water, the authorization of concessions for the use of this resource for mining constitutes the main source of income for this concept of the Ministry of Environment and Natural Resources (SEMARNAT) and the National Water Commission (CONAGUA). According to data from the Mining Chamber of Mexico (CAMIMEX), around 50% of government incomes from payment of rights for the use of water in the country are those contributed by mining companies. The Mexican territory is divided in four availability zones and, depending on the zone in which it operates, is the amount that concessionaires must pay for each cubic meter. Mexican mining pays up to MXP $26 for each cubic meter of water, while the average for the different industries is MXP $14. Municipalities pay only MXP $0.58. Meanwhile, the agricultural and livestock sectors, which are the main consumers in the country, do not pay rights for concessions for the use of water and despite this, these users tend to blame mining for the shortage. In Mexico, there are two types of concessions for the use of water: groundwater (located in subsoil aquifers) and surface water (found in rivers and lakes). According to CONAGUA, the main uses of this water resource are agricultural and livestock, which together consume approximately 76.7%; It is followed by urban public use, which is equivalent to 14.1%; the use for electricity generation with 5.1% and industries, whose consumption amounts to 4.1%. Of this amount, 0.9% corresponds to the mining sector. It refutes the myth about water consumption in mining.
- Alamos Gold Inc, GoGold Inc, Aztec Minerals Corp, Silver Tiger Metals Inc, and Minaurum Gold Inc reported the best drilling intercepts in Mexico on the third week of November, 2022. Details are shown in the table below:
- Aztec Minerals Corp., reported results for five drill holes from the recently completed phase 3 drill program at its Cervantes project in Sonora. Highlights of the drilling include hole CAL22-027 in the West-Central area of the California Zone with 0.68 g/t Au over 120m; and hole CAL22-029, a step out extending the California Zone to the North, with 0.77 g/t Au over 57m. These results have expanded the footprint of the known extents of the mineralized and altered California quartz feldspar intrusive complex to the North. “The area currently being drilled measures approximately 900 meters long E – W by 730 meters wide, with demonstrated, continuous mineralization of up to 170 meters in depth. The porphyry gold-copper mineralization is still open in all directions”.
- Tocvan Ventures Corp., announced that initial drilling is ongoing at its El Picacho project in Sonora. The drilling program is focused on two primary areas within the San Ramon prospect: Las Guijas where underground chip samples range from 0.5 to 8.2 g/t Au, with an average of 3.6 g/t Au, and San Ramon where underground samples range from 0.3 to 22 g/t Au, with an average of 5 g/t Au. The property is currently permitted for 14 drill pads. El Picacho is host to several other target areas permitted for drilling that span across the 24 km2 project area.
- Minaurum Gold Inc., provided an update on the underground rehabilitation work at the historical Promontorio mine within its Alamos Silver project. It informed that has successfully accessed and is dewatering the main haulage level along with clearing crosscuts in the El Tirito area of the mine, which lies approximately 300m from the Promontorio adit entrance. Approximately 200 tonnes of ballast and 50 tonnes of backfill have been removed from the first 300 m of the haulage level and stockpiled outside the mine entrance. Three of the five service holes that were drilled to provide air, water, and electricity to facilitate underground rehabilitation efforts intercepted the Promontorio Vein. The most significant drill intercept encountered 98 g/t Ag, 3.6% Pb, and 7.9% Zn over 5.8m. In addition, sampling and mapping of dumps at Promontorio revealed a boulder of massive sulfide vein assaying 3,320 g/t Ag, 54.7 g/t Au, 25% Cu, 6.5% Pb, and 1.1% Zn. “The boulder, measuring roughly a meter across, is an indication of the type of grades exploited by early miners at Promontorio”.
- Starcore International Mines Ltd., reported Q2, 2022 production and financial results from its San Martin mine in Queretaro. The company milled 57,165 tonnes of 1.46 g/t Au and 13 g/t Ag with metallurgical recoveries of 87.14% and 47.86% respectively, to produce 2,452 Oz AuEq.
- MAG Silver Corp., announced Q3, 2022 production and financial results from its Juanicipio project in Zacatecas, where it owns 44% of the property and Fresnillo plc owns the remainder 56%. The company reported on a 100% basis, that 180,808 tonnes of 513 g/t Ag were processed through the Fresnillo and Saucito plants to produce 2.42M Oz Ag, 4,901 Oz Au, 3M Lb Pb, and 4.56M Lb Zn. MAG reported a net income of USD $8.23M and cash of $USD 39.5M (Juanicipio had cash on hands of $USD 18.2M). Pre-commercial production sales totaled USD $49.7M, less USD $18.1 in mining and transportation costs and USD $6.4M in depreciation and amortization charges, netting USD $25.2M in gross profit by Juanicipio. The company also reported a cash balance at the end of the quarter of USD $18.2M down from USD $37.5M at the end of Q2, 2022.
- US Antimony Corporation reported September-October production results. The company milled 1,116 tonnes of 0.87 g/t Au and 96 g/t Ag from its Los Juarez Mine in Querétaro. In addition, the company announced that assay results from the previously announced soil sampling and rock chip programs on the 1km x 3 km grid at Los Juarez have been received with analysis values for Sb, Au, Ag, and trace elements. These results are being tabulated and assessed. Geologist and Geophysicist in Mexico have just completed the Geophysical Survey and are in the process of interpreting the results and generating a report. This report may be available prior to Q4 but most likely will be published early in Q1 of 2023.
- SilverCrest Metals Inc., reported Q3, 2022 production and financial results from its Las Chispas project in Sonora. The company produced 4,121 Oz Au and 373.5K Oz Ag (731.6K Oz AgEq) and had its first metal sales of 140.3K Oz Ag at an average price of USD $19.38 per Oz Ag, generating USD $2.7M in revenue. As of September 30, 2022 the company remains well-funded with cash and cash equivalents of USD $88.6M, and a debt balance of USD $90M.
- Vizsla Silver Corp., closed its previously announced bought deal financing of 23.8M units of the company at a price of CAD $1.45 per unit for gross proceeds of $CAD 34.5M. Net proceeds will be used to advance the exploration and development of its Panuco project in Sinaloa, including the delivery of an updated mineral resource estimate in Q4, 2022, as well as for working capital and general corporate purposes.

- GoGold Resources Inc., released strong results from the new drilling program at its Los Ricos South Main Area and at the newly acquired Eagle concession in Jalisco. Highlights of the drilling include hole LRGG-22-209 collared at Los Ricos South Main Area with 3.15 g/t Au and 276 g/t Ag (6.84 g/t AuEq or 513 g/t AgEq) over 33.2m, including 30.19 g/t Au and 2,588 g/t Ag (64.69 g/t AuEq or 4,852 g/t AgEq) over 3m, including 73.10 g/t Au and 5,620 g/t Ag (148.03 g/t AuEq or 11,103 g/t AgEq) over 1m; and hole LRGG-22-043 collared at the Eagle Concession with 0.67 g/t Au and 78 g/t Ag (1.72 g/t AuEq or 129 g/t AgEq) over 8.2m, plus 1.32 g/t Au and 216 g/t Ag (4.20 g/t AuEq or 315 g/t AgEq) over 20.7m, including 2.73 g/t Au and 428 g/t Ag (8.44 g/t AuEq or 633 g/t AgEq) over 9.3m, including 7.89 g/t Au and 999 g/t Ag (21.21 g/t AuEq or 1,591 g/t AgEq) over 2.5m, including 17.20 g/t Au and 2,130 g/t Ag (45.80 g/t AuEq or 3,420 g/t AgEq) over 0.70m. The purpose of the program is to better define the very high grade portions of the current deposit that may be amenable to bulk underground mining. “The Company exploration team has been completing detailed mapping and sampling at Jamaica over the last year and sees the same structure that was drilled in the main zone at Los Ricos South extending for several kilometers over the Jamaica concessions. This offers the potential for an additional bulk tonnage target in Los Ricos South, with continuity from the Main Area and Eagle”.
