This thesis reviews in details the niche industry of tantalum production.
Auxico signed a Memorandum of Understanding with Aucito S.A.S., a Colombian company, concerning the Villa Kelly Property in the Department of Bolivar, Colombia. The Villa Kelly Property covers an area of 92.2 hectares. According to the report written by M.Sc. Eng. Rene Florencio Lugo Primelles of ITKnowLogics S.A.S, a total of 12 veins have been prospected on the Property, and limited sampling of these veins has resulted in values up to 200 g/t Au. The Kelly vein has a shaft down to 14 metres and had been exploited from 2011 until 2014. There are 40 artisanal miners currently on the Property. – WED 14 OCT, 2015

"During its fifth phase, GEF developed a strategy to support and inform the negotiations for the global mercury agreement that funded mercury projects and programs. The projects helped to advance the devel- opment of the global mercury instrument and improve the ability of countries to implement the provisions of the instrument."
The Zamora Silver Property (“Zamora”), according to historical records is characterized by fifteen mines, ten of which were visited by the author of this report. All of the mines and/or prospects which will be described in this report have varying degrees of exploration, development and production. One of the properties which is mentioned in different parts of the report is referred to as La Franca. La Franca was visited and sampled by the author even though it does not belong to Auxico Resources Canada Inc. and the reason for this is because it lies within the Campanillas Claim and contains a high-grade sample of silver and gold (Sample no. B00127720, 1.72 kg/t Ag, 12.96 g/t Au).
The present report includes the results of contractual exploration work on the Mineral de Zamora property conceded to Mr. Juan Torres Orozco, developed and financed as part of the support program to the small mining companies of the Mineral Resources Board (Consejo de Recursos Minerales). This program is developed through management of exploration and carried out by the Offices of each State. The concession owner has realized the excavation work in the mine as a subcontractant and the people working for this Office have directed, supervised and interpreted the results.

We sometimes hear the term “mercury-free world” which seems a contradiction because mercury is an element. Thus, mercury always will be present. What can the inter- national community do about this?, by UNEP
