ON MEXICO ISSUE

• Orla Mining Ltd., Gatos Silver Inc., and Minaurum Gold Inc., reported the best drilling intercepts in Mexico on the fourth week of January, 2024. Details are shown in the table below:

ON EXPLORATION

• Infinitum Copper Corp., commenced a drilling program at its flagship La Adelita project, Sonora. The program will consists of 15 diamond holes for a total of 2,500m. Objective of the drilling program is to expand the size of the high-grade mineralized area at Cerro Grande zone as well as test for mineralization at depth in the Las Trancas zone.
• Minaurum  Gold Inc., released 2023 drilling results from the last six holes drilled at La Adelita project in Sonora. Hole AD-23-0034 encountered sporadic mineralization across multiple horizons: 0.08% Cu, 0.2 g/t Au, 16 g/t Ag, and 0.7% Zn over 3m, plus 0.40% Cu, 0.46 g/t Au, 86 g/t Ag, and 0.26% Zn over 0.95m, plus 0.117% Cu, 1.03 g/t Au, 30 g/t Ag, and 0.18% Zn over 2.80m, and plus 0.90% Cu, 0.18 g/t Au, 43 g/t Ag, and 0.33% Zn over 4.05m.
• Tocvan Ventures Corp., reported results of 75 rock chip samples from its Picachos project in Sonora. The 75 samples average 0.6 g/t Au and 2 g/t Ag with the values up to 15.9 g/t Au and 32 g/t Ag. “A new mineralized trend extending over 1.6 km in length has been discovered marked by old historic workings and exposure of mineralized veins and shear zones”.
• Reyna Silver Corp., shared results from Artificial Intelligence (AI) optimization of existing geophysical data from the Guigui project in Chihuahua. Explore Tech´s proprietary AI algorithm highlight a strong, multi-layered magnetic anomaly southeast of the 0.5 sq.km sulphide- mineralized skarn footprint identified in 2022 drilling. Explore Tech’s platform first uses AI to identify and locate where a geophysical anomaly actually is and then design the optimum hole geometry to hit it. “The results reinforce existing geological thinking that the intrusive source for the district lies in that area and greatly enhance the area’s potential. Pads to drill the target are already permitted and accessible”.
• Angel Wings Metals Inc., provided an exploration update and filed a NI 43-101 technical report on its La Reyna project, Nayarit. La Reyna is a contiguous block of fully titled mineral claims hat consolidates most of the historical Aguila de Oro mining district, with rock chip samples returning from nil to 27.12 g/t Au and nil to 2,938 g/t Ag., as well as anomalous values of Pb, Zn, Cu, Co, Bi, and Mo. “Mineralization is hosted in an extensive area of alteration that has been mapped over 70 square kilometers and is host to numerous past producing shallow mine and gambusino workings. To date, over 20 prospects with highly anomalous gold and silver have been identified on the project. A ground geophysics program including 11.2 line kilometers of Induced Polarization and 2 line kilometers of HSMAT is underway over El Polo-Dolorosa. Data is being processed with a report including the sections and maps due in early February”.

ON FINANCING

• Bear Creek Mining Corporation closed its previously announced restructuring transaction with Sandstorm Gold Ltd. The Transaction is expected to improve the Company’s ability to produce free cash flow in the near term from the Mercedes mine in Sonora.

ON RESOURCES AND DEVELOPMENT

• Discovery Silver Corp., outlined its 2024 work program for its Cordero project in Chihuahua. The Feasibility Study (FS) is nearing completion and is expected to be delivered later this quarter. The FS will include an additional 35,000m of reserve definition and expansion drilling, the results from the FS metallurgical testwork program as well as additional geotechnical and hydrogeology data collected in 2023. The Company will also provide an updated resource estimate concurrent with the results of the Study. In Permitting, the Environmental Impact Assessment is under review and approval by the Secretariat of the Environment and Natural Resource (SEMARNAT), while the Change of Land Use (CUS) known as Estudio Tecnico Justificativo (ETJ) will be finalized in the coming months with formal submission of the CUS expected to be made by 3Q 2024. Impact assessment and power installation studies were completed in 2023 confirming that there is sufficient capacity in the existing power grid to supply the project with power for operations at peak throughput levels. In 2023 the Company secured the surface rights that correspond with the planned open pit and key infrastructure locations at Cordero. The two potential sources of water for the project are local groundwater and water from local water treatment plants in the region. The Company has completed a hydro geological assessment through its Mexican specialist consultant utilizing data from hydrogeology drilling and pump test wells. Initial results indicate the potential for sufficient local groundwater for Phase 1 of the project (mill throughput of ~25,000 tonnes per day). In 2024, the company plans to complete mapping and sampling of new target areas along with 2,500 m of drilling.
