I see this morning where Glencore has a position in Trevali Mining.

Trevali Mining is in Peru, like us, and are a junior, like us. Now here you see this monster trader/producer of commodities, take some of its precious time to look at a junior. Here is who Glencore is;

Here is the project that Glencore is investing in when partnering with Trevali;

Now read this interesting part;

The Company's production decision is based only on Indicated and Inferred Mineral Resources and not Mineral Reserves and do not have demonstrated economic viability. Inferred Mineral Resources are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is therefore no certainty that the conclusions of the production decision will be realized. Additionally where Trevali discusses exploration/expansion potential, any potential quantity and grade is conceptual in nature and there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource

------------------------------------------------------------------------

So you see here is an unproven deposit being gone ahead on when it is not sure that it will even be viable. All Trevali really has is a resource estimate, yet there is the considerable Glencore interest.

The moral of the post;

The big guys are always watching and they can move at anytime along the proving up stages of a company.

IMO
