SUM has Carbonatite Deposit as well one of which is very close to CBMM,

Another project with Similar grades to Ecuador and much more:

SUMMIT TRANSFORMATIONAL BRAZILIAN NIOBIUM, RARE EARTH & LITHIUM PORTFOLIO HIGHLIGHTS:

•JUAZEIRINHO (Nb, REE),
•EQUADOR (Nb, REE),
•ARATAPIRA (REE),
•SANTA SOUSA (REE),
•T1/T2 (REE)
•HERCULES NORTH & SOUTH (Li)

So far most only know the Ecuador project.

Although the Juazeirinho project has similar Niobium grades to the Ecuador project.

Then there's SUM's Carbonatite Deposit:

SIGNIFICANT SCALE SURFACE SAPROLITE CLAY SYSTEM UNCOVERED AT ARATAPIRA

REE PROJECT HIGHLIGHTS:

• It lies between CBMM’s World-Class Niobium & ultra-high-grade hard rock REE deposit and Mosaic’s Phosphate & REE deposit, which may provide sources for REE-enriched saprolite clays at Aratapira.

• The project spans parts of the Alto Paranaíba Igneous Province (APIP), which accounts for over 97% of global niobium production and consists of major carbonatite complexes, kimberlites, lamproites, and minor alkali-related intrusions.

It's only around 12km from CBMM,
And less than 10km from Mosaic....
