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”.

US Antimony Reports Strong Production – February 2018

us antimony reports strong production_feb 2018

THOMPSON FALL, MT / ACCESSWIRE / February 5, 2018 / United States Antimony Corporation (“USAC,” NYSE American: UAMY) reported estimated sales for December 2017 and January 2018 were as follows:
Product December 2017 January 2018 % Change
Antimony pounds 76,868 212,764 +177%
Zeolite short tons 909 1,337 + 47%

Antimony sales were 135,896 pounds or 177% greater in January 2018 than December 2017 due to the fact that customers do not want large inventories at year end. USAC’s Mexican production has been more meaningful as the North American supply of raw materials has slowed down.

Evrim Resources samples 9.4 metres grading 7.4 g/t gold in first trenching results from 100%-owned Cuale gold project

2018-01-18-nr-evm-v8lkz1

Vancouver B.C. – January 18, 2018 Evrim Resources Corp. (TSX.V:EVM) (“Evrim” or the “Company”) is pleased to announce the first trenching results from its 100%-owned Cuale high sulphidation epithermal gold project in Jalisco, Mexico.  This preliminary exploration program was undertaken in December 2017 to define the extent of the La Gloria high sulphidation prospect and comprised three trenches over a distance of 300 metres within a core zone where previous rock chip sampling had defined gold mineralization.

U. S. ANTIMONY REPORTS APPROVAL OF LOS JUAREZ LEACH PLANT PERMIT

US Antimony 4 December 17

December 4, 2017. Thompson Falls, Montana. United States Antimony Corporation (“USAC”, NYSE American “UAMY”) reported that SEMARNAT (the equivalent of the U.S. EPA) has issued USAMSA (a wholly owned subsidiary of USAC) the permit for a cyanide leach plant for the Puerto Blanco mill in Guanajuato, Mexico.

The plant is designed to recover gold and silver from the pilot flotation mill tailings of the Los Juarez gold-silver-antimony deposit in Queretaro, Mexico. The deposit is 3.5 kilometers in length and over 1 kilometer in width. It has all the signature elements of the Carlin gold mine and the Robert’s Mountain over-thrust belt in Nevada. The deposit has been owned by two major mining Companies but has never gone into production due to the complex metallurgy. USAC has solved the metallurgical problem with the floatation product by adding an alkaline leach circuit.  A second issue was that the mill only recovered 30 to 50% of the gold and 60 to 80% of the silver in the flotation concentrate. Test work showed that these values could be recovered by a cyanide leach of the mill tailings. USAC has finally gotten the permit for the cyanide leach after many years. Construction of the leach circuit has commenced. Initial projects will include a plastic liner for the tailings pond and construction of the leach plant building. In Montana, construction of leach plant equipment is underway.
