ON MEXICO ISSUES

  • Mexican fiscal authorities and Canadian mining companies maintain a table of dialog on delayed tax reimbursements for $360 M, according to José Antonio Meade (head of the IRS equivalent agency) and Bill Morneau (Canadian Finance minister). They pointed out at a joint press conference that the situation is to be solved by dialogue and under the legal framework, with the aim to avoid this situation to have an effect on Canadian investment in Mexico. Bill Morneau pointed out that the common objective is to keep Canadian companies taking opportunities in the mining sector; while Meade said that the intention is to create an adequate investment environment for companies to feel at ease, with confidence in Mexico as a country under the rule of law. According to the latter, 40% of Canadian investment in Mexico is on the mining sector.

ON EXPLORATION

  • Canuc Resources Corp. released results from the phase I drill program at its San Javier project in Sonora.

  • Mexican Gold Corp. filed at SEDAR the technical report on the mineral resource estimate for its Las Minas project in Veracruz. The report states an inferred resource of 719 K Oz AuEq contained in 10.3 M tonnes @ 2.17 AuEq and total measured and indicated resources of 304 K Oz Au in 4.97 M tonnes @ 1.90 g/t AuEq.

ON DEALS AND CORPORATE ISSUES

  • Endeavour Silver Corp. and Capstone Mining Corp. entered into an agreement under which Endeavour has the right to explore and mine for precious metals above 2,000 m elevation (meters above sea level, or “mas”) on Capstone’s the Toro del Cobre claim, adjacent to Endeavour’s Calicanto concessions in Zacatecas. Endeavour granted Capstone the right to explore and mine for base metals below the elevation of 2,000 m (mas). The deal was done on the understanding of mineralization zonation in the district, with precious metals mineralization over 2,000 m elevation and base metals occurring below that mark (Note of editor.- This type of deal is not common in Mexico, and reveals a “Think outside of the box” attitude by both companies).
  • Magellan Gold Corp. and Rose Petroleum PLC signed a definitive and binding stock purchase agreement on Magellan’s acquisition of the mineral processing mill operation in San Dieguito de Arriba, Nayarit. The purchase total consideration is US$1.5 M, consisting of $1.0 M in cash and $500 K in Magellan stock, of which $100 K in cash has already been paid. Magellan has arranged $900 K in irrevocable bridge loans in support of its option to purchase the 200 tpd mill.
  • Advance Gold Corp. is to acquire a 100% interest in the Tabasqueña silver mine in Zacatecas. Upon receipt of regulatory approval, Advance will issue Hot Spring Mining, a Mexican based corporation, 1 M common shares. Hot Spring is to retain a 2.5% NSR, of which Advance has the right to buy 1.5% at a rate of CAD$500 K per 0.5%.
  • Dyna Resources Mexico, S.A. de C.V. announced that it has received a favorable ruling with the dismissal by a court in Veracruz of Goldgroup Resources Inc.’s amparo trial challenge to the US$48 M damages award previously granted in favor of Dyna.
  • Orex Minerals Inc. was made aware that Canasil Resources Inc. has been named in a lawsuit brought by Pan American Silver Corp. with the BC Supreme Court, regarding the mineral claims making up the Sandra Escobar project in Durango. Orex earned 55% ownership on the project from Canasil, interest that could be impacted if Pan American Silver’s claim is proven.
