 ON MEXICO ISSUES

  • Mexican mining projects raised interest for up to USD$ 8M of investment by companies from Canada, USA, Peru, Colombia, and Australia. According to the head of mining in the country, before realizing the investments, it will be necessary to carry out the work of convincing the surrounding populations. He said: “The type of mining we want is to pay taxes, be socially responsible and achieve economic benefits so that it reaches society and the settlement is public.” He insisted that the presidential mandate is that mining concessions will not be canceled and that the commitments acquired in the past will be honored. Among the areas with the greatest potential are in the south-southeast of Mexico, specifically the states of Oaxaca, Guerrero and Morelos, among others, with products such as Ag, Au, and Cu. The Ministry of Economy reported that the mining-metallurgical sector in Mexico contributes 4% of the national Gross Domestic Product. While in the world our country is the largest producer of Ag; it is among the top 10 producers of 16 different minerals: silver, bismuth, fluorite, celestite, wollastonite, cadmium, molybdenum, lead, zinc, diatomite, salt, barite, graphite, gypsum, gold and copper.

Millrock Begins Second Round of Drilling at La Navidad Gold Project, Sonora State, Mexico

Millrock_16052018

VANCOUVER, BRITISH COLUMBIA, May 16, 2018 – Millrock Resources Inc. (TSX-V: MRO, OTCQX: MLRKF) (“Millrock”) is pleased to report that a second round of drilling is beginning at the La Navidad gold project. The project, located in Sonora State, Mexico, 100 km north of the City of Hermosillo, targets orogenic, bulk mineable, run-of-mine, oxidized deposits that could be processed by heap leaching. Exploration work is being funded under an option to joint venture agreement by Centerra Gold Inc. (“Centerra”). The core drilling program will consist initially of 1,650 meters in seven holes, ranging from 150 to 250 meters in depth. These holes will target the large, strong, gold-in-soil anomalies previously identified at the Cobre and Crossover prospects. Recent trenching has confirmed bedrock gold mineralization at surface in these prospect areas. Additionally, at least one hole from the initial program completed in late 2017 will be deepened to test for further mineralization at the Anchor prospect. Results of that program were reported in a prior press release here. Contingent upon results of the upcoming drilling phase, the drilling program may be extended.
