You're asking me as if I am part of the company (which I'm not) and that I would have more answers than anyone else.

I read the same announcements (properly read it appears) available to everyone else.

Not much is mentioned about the 301162/2011 tenement in that announcement, I'm thinking given this was a whole package of 6 tenements auctioned off by the Govt. that they were all lumped in together and the company got what they got but the main target
was that directly adjacent and north tenement of Equador (848283/1999) and if they wanted that then they had to get the whole package being auctioned.

Looking at the Brazil Mining Concessions, the whole region is full of Tantalum exploration, especially around that 301161/2011 tenement. The DADO NAO CADASTRADO means currently not registered (which is noted in the announcement SUM is waiting for Govt. approvals to finalisation on the whole package before undertaking work.)

One of the tenements next to that newly acquired one; many of them are TANTALITA (tantalum)



I'm not a gem or geo expert but those don't look like gems in the video, look like the same black rock pieces that they've been showing from the current Equador tenement. Just because there's an establish gem mine few kms north doesn't mean much, the area is full of all sorts of resources; lithium, REEs, gems, Niobium, Tantalum...etc.



As per that social media post from SUM:


"Summit’s Chief Geologist, Stuart Peterson, will be on-site at the Equador Niobium project later this month."
