Perseverance Project


Perseverance is in northeastern Minas Gerais, in the geological extensions of the Lithium Valley (Figure 1), a politically defined area including the towns of Salinas and Araçuaí that lie adjacent to the mines and JORC / NI43-101 compliant resources of CBL, Sigma Lithium and Latin Resources.  Belo Horizonte is the regional capital for the state of Minas Gerais. Numerous artisanal mines exist within the tenements (Figure 2).

A number of high profile Lithium explorers & developers are located in the region including the well-known Sigma Lithium (TSXV:SGML) and Latin Resources (ASX:LRS).

The Araçuaí Orogen has a series of characteristics that make it prone to lithium mineralisation. It has a lower Proterozoic to Archean basement at least to the west of the suture shown on Figure 3 below, a protracted time at high temperatures, probably underplating and intrusion by mafic magmas and a series of granites known to be lithium prone that are in places only partially unroofed.

Structural interpretation in the Araçuaí Orogen undertaken by the Vendor’s structural expert has identified likely locations for concealed granites that may be at shallow depth where the sediments in the target zones are likely to be lithium pegmatite bearing. Known mineralisation in the Araçuaí Orogen includes not only common pegmatite minerals but some occurrences of minerals indicative of LCT type pegmatites.
