ON MEXICO ISSUES

  • Napoleon Gomez Urrutia, mining leader and senator of the MORENA party, declared that is ready to go over the mining companies that do not pay enough taxes, pollute the environment and have too ground in mineral concessions. The mining leader is reviewing mineral concessions and said that mining companies should contribute to the government with more revenues. He also said that the Mining Law of Mexico has to be regulated in accordance with the interests of the country. “We are looking at the cancellation terms for a concession and its extension, because 50, 100 years is too long,” he explained. The senator also mentioned not to have in mind any particular tax for companies.

ON MEXICO ISSUES

  • In AIMMGM’s past conference in October, Fernando Alanis from CAMIMEX (Cámara Minera de México) presented figures from the mining industry in Mexico. Mineral royalties collected US$220 M in 2017, adding up to US$631 M on the last four years. An additional US$248 M were invested by companies in the communities and environment where they are located. Just in mining duties over concessions amounted to US$132.9 M. In the attractiveness index for investment, Mexico has gone from the 11th place in 2011 to the 44th place in 2018. At the same time our direct competitors for investment in the mining industry are doing better, Peru passed from the 39th to the 19th position, and Chile from the 6th to the 8th position. Points suggested to make of Mexico a mining country include improvements in security, a better infrastructure (railways, ports), certainty on land rights, a common ground with other mining countries in fiscal terms, administrative efficiency in the application and issuing of mining concession titles and certainty and transparency in the timely granting of permits.

ON EXPLORATION

  • Prize Mining Corp. engaged a consultant to compile a GIS database for a regional exploration program on its 17,659 ha Manto Negro project in Coahuila. The 3,000 m drill program continues with its focus on the Granizo and Pilar Grande areas.
  • Southern Silver Exploration Corp. reported drill results from its CLM West claim group, adjacent to its Cerro Las Minitas project in Durango. One of three holes intercepted 3.0 m @ 168 g/t Ag, while the other two returned strong (up to 0.1%) arsenic and antimony anomalies. “The mineralization represents the first significant silver intercept identified on the CLM West claim group where drilling is targeting new Ag-Au epithermal systems”.
  • Kootenay Silver Inc. staked 2,857 ha in Chihuahua, creating the Mecatona project. The Ag dominant epithermal system is hosted in veins and breccias, with one anomalous structure running for more than 1.7 km, and another zone hosting stockworks and quartz veinlets in an 80 m wide argillic alteration zone. Results from 78 samples collected at the property are as high as 735 g/t Ag, 6.94 g/t Au, 3.5% Pb, 8.0% Zn.
  • Excellon Resources Inc. received title to concessions that increases its land position to over 45,000 hectares on its consolidated “Evolución” property, within the Miguel Auza district in Durango, along strike to HECLA’s San Sebastian mine. As announced in previous press releases, initial drilling has already shown broad mineralized intersections with anomalous Au, Ag, Pb, Zn, “including discrete higher‐grade zones of carbonate veining, bladed calcite and silica with galena, sphalerite and pyrite”.
  • Colibri Resource Corp. described the El Mezquite and Jackie projects in Sonora, its new properties through the acquisition of Yaque Minerals S.A. de C.V. from On Top Capital Ltd. The 180 hectares Mezquite project contains an alteration zone 2 km by 1 km , within which are at least four zones of sulfide oxidation related to contacts with a silicified feldspar porphyry. Assay results from 321 rock chip samples returned 42 samples over 0.1 g/t Au, averaging 0.74 g/t Au and up to 3.41 g/t Au, 198 g/t Ag. The 1,130 ha Jackie project is 2 km south of El Mezquite, and abuts to the east with the Santana project, owned by Minera Alamos.

To date 756 samples have been collected, identifying a series of low-sulfidation quartz veins and breccias. A regional exploration program was launched to search for additional veins.
  • Galore Resources Inc. has been granted permits to begin a 12-hole, 3,000 m diamond core drill program at its El Alamo claim in Zacatecas. El Alamo consists of Cretaceous sediments, mostly limestone with some siltstone and chert, and major faults bounding the project. Alteration and mineralization are represented by silicification and iron-oxide bodies after sulfides. Some of the higher grade gold values are associated with extensively iron-oxide jasperoid breccias. A shallow drill percussion camping collared 35 holes in 2012, and defined a 500 long by 200 wide target zone.

ON MINING

  • Consolidated Zinc Ltd. presented its September 2018 quarterly activities report. The Group entered a 12 month toll treatment and offtake purchase agreement with Grupo Mexico to treat its ore at the Santa Eulalia’s concentrator plant, with mining at the Plomosas mine in Chihuahua beginning on September 13th 2018.

ON EXPLORATION

  • Riverside Resources Inc., completed 11 N-S lines for soil sampling which returned strong multi-elements anomalies with Au, Pb, Cu, and other key elements. These results along with previous exploration work have outlined four new target areas on its Cecilia project in Sonora. Target 1 is a 4km long by 300m wide target where previous rock sampling has found up to 2 g/t Au in silicified conglomerates , but the soil anomaly is open in both directions beyond the 4 Km and more than 800m wide. Target 2 is a NE trending Ag, Pb, Au, Zn, Sb, Hg and Cu soil anomaly over 2km long and 600m wide in rock cracks with faults and host veining displaying a series of NW striking feeder dikes. Target 3 is a 1km long by 500m wide Au-Zn with minor Ag, Cu, Pb and Bi soil anomaly associated to a N-S trending fault system intersecting Paleozoic limestones. This target is also along the border edge of a magnetic high reported in a regional government geophysics survey likely associated with Pre Cambrian granitic basement.  Target 4 contains “high-grade gold samples in soils and alteration with jasperoid, silicification, and carbonate veining of the Paleozoic limestone that gives a potential limestone hosted Au with anomalous soil assays of Zn, Pb, Ag and Mn”.
  • Kootenay Silver Inc., announced that its partner Capstone Mining Corp., has commenced an exploration program on its la Mina project in Sonora. The exploration program will consists of detailed mapping and rock chip / stream sediment sampling to generate potential drill targets.
