Brazilian Rare Earth & Uranium Projects
CORE’s Brazilian Rare Earth & Uranium projects cover a combined area of ~800km² of prospective ground across Paraiba, Parana, Goiás and Rio Grande do Sul, Brazil.
CORE has acquired high-quality projects and continues to assess additional areas of high geological potential within Brazil.
CORE’S experienced, Brazil based geologist and in-country team are conducting robust field reconnaissance programs at Sao Jose, Amorinopolis, Grande and Tunas projects, driving a strong and focused exploration strategy in the top-tier mining jurisdiction of Brazil.
Amorinopolis Uranium Project – Goiás State
- CORE has pegged 17 contiguous licenses encompassing an area of 320km2
- The exploration rationale is that the regional granites are the potential source of any uranium in the area, with the sandstone unit acting as the host for any uranium which has been leached and concentrated from the granites
- CORE is actively targeting the sandstone unit, as well as any geological unconformities
- CORE has a preliminary exploration plan in place, consisting of surficial mapping, sampling, scintillometer surveys. In additional to geophysical surveys. These will be used to delineate drill targets
- CORE’s exploration team have successfully identified multiple uranium mineralisation occurrences. Through a systematic and meticulous reconnaissance program, two distinct prospects have been identified
Sao Jose Uranium Project – Paraiba State
- Identified in 1970s, drilled with ~60 Diamond holes
- 2009 Resampling of drill core produced ranges up to 3,450ppm (0.35% U3O8) (average of all 725 samples was 492ppm)
- Interpreted ~2000m strike length, Mineralization down to 250m
- Unverified Inferred and indicated Resource @ avg 1,200ppm U3O8 and 22Mlb combined resource using a 500ppm cutoff
- 300ppm is currently considered the minimum economic grade
- REEs have been identified within the deposit and studies were completed due to the Government control of Uranium assets at the time
- CORE has pegged ground surrounding this historic deposit, with mineralization interpreted to extent into CORE’s tenure.
Grande Uranium Project – Rio Grande do Sul
- CORE has pegged two areas within Rio Grande do Sul for a total of 364.52km2.
- Grande is prospective for sandstone and conglomerate hosted uranium deposits, as it is within 4km of a uranium occurrence identified by the INB in the northern part
- CORE is targeting an extension of the same lithology (Rio Bonita and Sanga do Cabral Formation) which hosts this occurrence
- The exploration rationale is that the regional granites are the potential source of any uranium in the area, with the sandstone unit acting as the host for any uranium which has been leached and concentrated from the granites
- Reconnaissance program underway, consisting of surficial mapping, sampling, scintillometer surveys will be used to delineate drill targets
Tunas Rare Earth Elements Project – Parana
- CORE’S Tunas Project tenure surrounds the largest alkaline intrusive complex in Southern Brazil and covers an area of 18.32km2
- Field operations with a program of stakeholder engagement followed by mapping and reconnaissance sampling have been completed with airborne radiometric data showing strong thorium > uranium – potassium, signature typically favourable for REE deposits
- Significant REE in preliminary soil results: Total Rate Earth Oxide (REO) assay results of 2,921ppm
- Systematic auger soil sampling program underway to define drilling targets
