ON MEXICO ISSUES

  • No relevant news.

 ON EXPLORATION

  • One World Lithium Inc., presented results from a geophysical survey conducted on its Salar del Diablo project in Baja California Norte. Three very large and highly conductive zones were identified by a Volterra TEM in loop survey. Zone 1 is > 100m thick and covers six square km. Zone 2 surrounds Zone 1 and is < 100m thick and covers 24 square km. Zone 3 is estimated to be approximately 200m thick and covers > 30 square km.
  • Colibri Resources Corporation, reported RC drilling results from its Pilar project in Sonora. Significant results are 61m of 0.75 g/t Au, including 1.5m of 17.3 g/t Au; 6m of 0.68 g/t Au; 3m of 5.40 g/t Au; and 34.5m of 0.32 g/t Au. The drill results extend the Main Zone´s mineralized envelope to the northwest and southeast by upwards of a total of 145m. It represents an increase of 52% in the length of the Main Zone. Potential is open in both directions of the mineralized zone.
  • Minaurum Gold Inc., discovered the extension of the Promontorio-Quintera and Nueva Europa veins at its Alamos Silver project in Sonora. The Promontorio-Quintera vein was mapped and extends for 1km and is cut-off and down-dropped by a northwest trending fault while the Nueva Europa vein was mapped for over 600m. The extensions have the potential to host virgin mineralization at depth. Surface sampling on Promontorio South vein returned 1.1m of 181 g/t Ag and 1.06% Cu, while at Nueva Europa South vein, a 0.8m long chip rock sample returned 52 g/t Ag and 0.54% Cu, and a dump sample returned 91 g/t Ag and 1% Cu.
  • San Marco Resources Inc., identified many new significant Cu-Ag occurrences at its Chunibas property in Sonora; conducted a portable X-ray fluorescence rock analysis on an area of 300m by 1,400m, indicating anomalous to significant copper values, and received assays from ninety six rock chip samples ranging from 0.1% to 1.34% Cu. The company also carried out a saw-cut continuous channel sampling returning 30m of 0.16% Cu and 3 g/t Ag, and 22m of 0.17% Cu and 2 g/t Ag. Now, the mineralized NW-SE corridor is 1.7Km long by 300m wide, and remains open along strike and down dip. San Marco has begun preparations to perform a drill program at its Chunibas property.
  • Millrock Resources Inc., provided and exploration update on their Mexican properties in Sonora and San Luis Potosi. In Sonora, at La Navidad project, a 2,900m drilling program has been recently completed to test the El Cobre and the Crossover targets. Complete results are anticipated in early August. At El Picacho project (Orogenic gold), drill targets are emerging from the exploration work conducted in the first half of 2018. The company has authorized a drill program to begin later in the summer. At Batamote, good geological signs of a porphyry copper deposit have been identified and a major company is currently evaluating the property. At Los Cuarenta project (low-sulphidation epithermal Au-Ag), Millrock has acquired an option to purchase a key internal claim called Santa Rosalia. Drilling targets have been developed and drilling permit is in place. In San Luis Potosi, the Guadalcazar project hosts a high-grade Ag-Pb-Zn skarn with good drill intersections and historic mine workings, with potential to expand the known deposit. Millrock has received an offer to form an option agreement.
  • Azure Minerals Limited., provided an exploration update on its Sara Alicia and El Alacran properties in Sonora. At the Sara Alicia project, the stage 2 drilling campaign confirmed near-surface, high-grade Au-Co mineralization with maximum grade returning 53.8 g/t Au over 0.90m and 2.82% Co over 0.80m. The best Au interception was 19.6m of 8.6 g/t Au, including 15.3m of 10.6 g/t Au, while the best Co interception was 3.65m of 1.19% Co, including 1.5m of 2.66% Co. At the El Alacran project, the drilling campaign indicated the southern expansion of Loma Bonita epithermal Au-Ag system based on the presence of silicified zones covered by fresh-rock and high-resistivity geophysical anomalies extending to depth. At Cerro Colorado the company geologists identified the presence of porphyry-type alteration and veining with trace copper and molybdenum mineralization, warranting follow-up work. Teck will continue exploring the property with drilling planned to restart in Q3 2018.
  • Mammoth Resources Inc., announced drill results from its Tenoriba project in Chihuahua. Results are from the Masuparia area, in the central portion of the 6 km long trend of gold mineralization on the property. Significant results are 3m of 0.19 g/t Au and 10 g/t Ag in hole TEN 17-09 and multiple intersections in hole TEN 17-10 such as 4.5m of 0.42 g/t Au and 8 g/t Ag; 4.5m of 0.45 g/t Au and 3 g/t Ag, 22.5m of 0.35 g/t Au and 4 g/t Ag, 3m of 1.31 g/t Au and 50 g/t Ag, 3m of 0.65 g/t Au and 5 g/t Ag, and 24m of 0.31 g/t Au and 4 g/t Ag.
  • Discovery Metals Inc., reported underground channel sample results from the San Jose mine within its Puerto Rico project in Coahuila. Assay results represent 140m of workings and were collected at 3-5m intervals along both sides of the entire length of the developed workings. Mineralization is related to mantos, chimneys and faults. Mantos range from 0.5m to 1.5m in width (restricted by dimensions of workings) and are open in all directions laterally along strike and dip. Fourteen samples from mantos returned an average of 229 g/t Ag, 9.3% Pb, 17.6% Zn, and 0.3% Cu. Chimney widths range from 1m to 6m, with the main part of the chimney having a width of 5-6m, while the mineralized faults widths range from 0.4m to 1.4m, and are open along strike and at depth. Thirty three samples from chimneys and faults returned an average grade of 50 g/t Ag, 3.5% Pb, 4% Zn, and 0.8% Cu. The company is currently carrying out a detail structural study on the entire property to identify controls on mineralization. Additionally, it is planning to conduct a magnetic survey in preparation for drilling later in 2H 2018.
  • Kootenay Silver Inc., presented sampling results from its Copalito project in Sinaloa. Copalito is a low-sulphidation epithermal vein system. At least 4 main veins and numerous smaller veins have been identified, with individual veins found to be up to 15m wide and at least 2km long along strike. Eleven samples (5 chips and 6 grabs) on Cobriza vein returned grades from 47 to 2.5 kg/t Ag and 0.03 to 2.7 g/t Au, while twenty two samples on El Pilar vein returned grades from 2 to 166 g/t Ag and 0.04 to 1.05 g/t Au.
