Sulista Uncommon Earth District – Main scale, high-grade and strategic location
- District Scale: New drill outcomes affirm an in depth high-grade rare-earth system at shallow depths – with +7 km of cumulative mineralised strike over seven exploration corridors throughout the Sulista Uncommon Earth District in Bahia, Brazil
- Exploration Goal: Sulista covers an enormous ‘10 km by 2 km’ exploration goal space returning shallow, high- grade uncommon earth mineralisation outcomes throughout regolith, bedrock and outcrop vectors. Exploration Goal has now been estimated throughout the seven exploration corridors at Sulista
- Infrastructure benefit: The district is in a strategic location, with state freeway BR-330 traversing and connecting Sulista with the Camaçari Petrochemical Advanced, Bahia; 138 kV energy simply ~4 km, and expert workforce and companies ~12 km
Sulista East – Excellent uncommon earth assays throughout regolith, bedrock, and new outcrop boulders
- Massive-scale, shallow, high-grade uncommon earth system recognized with true thicknesses as much as 30 m over 500 m of strike, nonetheless open alongside pattern and at depth
- New drill highlights embrace grades as much as 9.6% TREO, with 15,695ppm NdPr, inside 16.6 m at 3.9% TREO from floor (STU1482, open at depth), and enormous intercepts 33 m at 3.8% TREO from 7 m (JITDD0036)
- Widespread mineralised outcrops with grades of as much as 10.5% TREO prolong Sulista East by +5 km to the south; newest drilling defines a steady, tabular bedrock uncommon earth deposit with grades over 3% TREO
- New discovery simply ~500 m north of Sulista East: ‘Monte Alto-style’ ultra-high-grade outcrop boulders at 32.1% TREO, present basic pathfinders to high-grade bedrock mineralisation
Determine 1: Sulista Mission: Drill examined deposits and precedence drill targets1
Sulista West – Outcrop Ridge drill program concentrating on high-grade extensions
- New 5,000 m diamond drill program is now underway at Sulista West, concentrating on a high-grade REE–Nb–Sc– Ta–U system beneath an intense floor geophysical anomaly
- Outcrop Ridge goal is anchored by outcrop grades as much as 20.6% TREO (R1255) and earlier drilling as much as 22.4% TREO, pointing to a second high-grade centre advancing in parallel with Sulista East
- Observe-up auger outcomes with grades as much as 15.6% TREO with 34,467ppm NdPr and 1,767ppm DyTb inside Sulista West Deposit cowl interval of 6 m at 9.9% TREO from 14 m (STU1813)
Sulista District Exploration Goal
Exploration Goal estimate of 12–18 Mt, with grades of 4–6% TREO, throughout seven exploration corridors throughout the Sulista District.
- Noticed thickness & grade distribution: At Sulista East ~70% of drill holes intersect mineralisation, with important intercepts displaying cumulative widths of 15–20 m and a length-weighted interquartile vary of three–5% TREO
- District-scale continuity from a number of pathfinders: >1% TREO auger developments, floor/airborne radiometric anomalies, broad gamma anomalies correlated with high-grade secondary monazite, and ultra-high grade outcrops/boulders outline a drill-ready strike over ~6 km
- Geological course of: Coexistence of a wealthy, coherent and constant tabular bedrock REE soften (~3.1% TREO), thick high-grade regolith above, and proximal Monte Alto-style boulders signifies a extremely potential magmatic and regolith system that repeats alongside strike
The potential amount and grade of the Exploration Goal is conceptual in nature. There was inadequate exploration to estimate a Mineral Useful resource, and it’s unsure if additional exploration will outcome within the estimation of a Mineral Useful resource.
Sulista Drilling Standing
- Sulista East: 44 core holes accomplished (4,737 m); 13 holes assayed and reported herein (1,188 m); 31 holes pending (3,549 m)
- Sulista West: 14 diamond holes beforehand accomplished (1,885 m), with assays beforehand reported for 11 holes (1,463 m) Together with as much as 22.4% TREO. New 5,000 m drilling program underway at Outcrop Ridge
- Sulista District: 61 new auger holes accomplished (1,040 m)
Subsequent Steps
- Drilling: Step-out program to increase the Sulista East pattern alongside the >1% TREO hall; systematic drilling over the Monte Alto-style boulder subject; advance Outcrop Ridge and precedence targets
- Geophysics: Execute high-resolution helicopter magnetic & radiometric survey
BRE’s Managing Director & CEO, Bernardo da Veiga:
“Our profitable exploration pathfinder mannequin continues to ship at our Sulista Uncommon Earth District – with the most recent outcomes confirming expansive, high-grade uncommon earth mineralisation with a transparent path to scale.
These distinctive outcomes additionally reinforce our conviction within the Rocha da Rocha Uncommon Earth Province. We now see the potential for this huge province to carry multi-district high-grade uncommon earth programs – and we’re initially of systematically unlocking this potential.”
