Explotación minera en el mar, opción o pesadilla
La explotación minera de fondos oceánicos será pronto una realidad. Sus impactos ambientales están siendo intensamente evaluados por instituciones académicas y agencias internacionales, mientras la ingeniería avanza lo suficiente para colocarla como opción viable y rentable, en muchos casos, superior a la minería en tierra. Crece la escasez de minerales metálicos y no metálicos en yacimientos terrestres accesibles y de costo aceptable, mientras el reciclaje es insuficiente y la demanda aumenta exponencialmente por la industria electrónica y la fabricación de baterías para vehículos eléctricos. Níquel, cobalto, tungsteno, platino, rodio, manganeso y otros metales son indispensables para nuevas tecnologías electrónicas, y el fósforo es insumo vital para la manufactura de fertilizantes esenciales en la agricultura. El impacto ambiental de actividades mineras en tierra llega a ser devastador en cuanto a ecosistemas y paisajes, deforestación, y contaminación de aguas, suelos y atmósfera.

CyPlus Idesa Sodium Cyanide Production Begins in Mexico
The new CyPlus Idesa sodium cyanide production plant was officially opened with an inauguration ceremony in Coatzacoalcos (Veracruz, Mexico) in the presence of Dr. Klaus Engel, chairman of the executive board of Evonik Industries and Patricio Gutiérrez Fernandez, chairman of CyPlus Idesa.
CyPlus Idesa is a joint venture between German Evonik and Mexican Grupo IDESA.
The new sodium cyanide plant has a capacity of 40,000 metric tons and uses state-of-the-art hydrocyanic acid and cyanide technologies. Special attention was dedicated to the compliance of all environmental and safety regulations, ensuring that production of sodium cyanide complies with the provisions of the “International Cyanide Management Code” (ICMC).
Gold and silver mining operations use sodium cyanide to extract precious metals from the mineral. Mexico is the number one producer of silver in the world and ranks among the top 15 producers of gold worldwide.
“The new local production facility will make us an even better and more flexible supplier for our customers in the region. The facility represents another important step in the growth strategy of Evonik,” said Engel.

Some incomplete test suggest the process can achieve 54% – 58% silver recoveries.
- Telson Resources Inc. informed that a pre-feasibility study (PFS) technical report has been filed on its Tahuehueto project in Durango. The project envisages a 790 tpd overhand cut and fill mine, and a 550 tpd flotation plant to produce Pb, Cu and Zn concentrates during the 21 year mine life, with annual production averaging 16.1 K Oz Au, 177.1 K Oz Ag, 0.9 M Lb Cu, 3.2 M Lb Pb and 5.6 M Lb Zn. The current probable mineral reserves stand at 3.3 M tonnes @ 3.4 g/t Au, 41.8 g/t Ag, 0.31% Cu, 1.1% Pb, 2.0% Zn. The study portrays a post-tax net present value (NPV) of $77 M (using an 8% discount rate), and pre-production capital costs of $32.2 M.
- Golden Minerals Co. announced a NI-43-101 compliant maiden resource for its Rodeo property in Durango. Two resource estimates were prepared, one for mill processing comprising indicated open pit resources of 0.4 M tonnes (0.83 g/t AuEq cutoff) @ 3.3 g/t Au, 11 g/t Ag, for a total of 46 K Oz Au, 0.2 M Oz Ag, with expected recoveries of 77% Au, 90% Ag; and a second scenario with an open pit heap leach processing, bearing indicated resources of 3.6 M tonnes @ 0.8 g/t Au, 12 g/t Ag containing 94 K Oz Au, 1.4 M Oz Ag and inferred resources of 3.6 M tonnes @ 0.4 g/t Au, 11 g/t Ag, containing 47 K Oz Au, 1.3 M Oz Ag, with recoveries of 60% Au, 70% Ag.
ON DEALS AND CORPORATE ISSUES
- Mx Gold Corp. has paid remaining installments (totaling $2.5 M) earning a 50% participating ownership interest and 45% net profit participating interest in the Magistral del Oro tailings project in Durango. “The Project includes a fully permitted, 500 tonne-per-day dynamic cyanide countercurrent system plant constructed in 2013 at a cost of approximately $4.5 million, which appears to be in excellent condition.”

Mexus begins work on its open heap leach pad with all permits in hand
CARSON CITY, Nev., April 25, 2016 (GLOBE NEWSWIRE) — Mexus Gold US (OTCQB:MXSG) (“Mexus” or the “Company”) announced today that the environmental and mining permits are complete and work has begun on the area that will become Mexus’ open pit heap leach mine. An area 300 meters by 100 meters is being cleared and leveled for the pad. (See Attached Photos) Mexus intends to open pit the shear zone where the Julio high grade quartz vein faulted to the west as identified by Director of Operations Cesar Lemas. The shear zone and the Julio quartz vein will be mined simultaneously with strict grade control. The shear zone ore has graded 1 to 5 grams per ton with the Julio assays running much higher and includes visible gold. Mexus believes that mining the Julio quartz vein from the surface along with the shear zone makes the most sense. The shear zone material will be crushed to ¾” minus then placed on the leach pad. The Julio high grade will go straight to Mexus’ crusher ball mill gravity recovery plant. The tailings from the gravity recovery plant will also be placed on the heap.
