Summary
Bravo Mining Corp. has announced strong Pre-Feasibility Study results for its Luanga Project in Brazil, reporting an after-tax NPV8% of US$1.45 billion and an IRR of 35.1%. The study includes a maiden Proven & Probable Mineral Reserve of 86.7 Mt grading 2.77 g/t PdEq for 7,731 kOz of contained PdEq, and improved metallurgical recoveries using Jameson Cell flotation technology. The company plans to advance permitting and a Definitive Feasibility Study, with an updated Mineral Resource expected in Q1 2027.
Reasoning: The Pre-Feasibility Study for the Luanga Project demonstrates robust economics with a significant after-tax NPV and IRR, supported by a maiden Mineral Reserve and improved metallurgical recoveries, marking a major de-risking milestone for the project.
Positive factors
- Strong economic metrics (NPV, IRR, payback)
- Maiden Mineral Reserve declared
- Improved metallurgical recoveries with Jameson Cell technology
- Vertical integration strategy with ZPE benefits
- Strategic geographical advantage and advancing permits
- Well-funded for next steps
Negative factors
- Mineral Reserve does not include 22,100m of 2026 infill and expansion drilling
- PFS is based on a 2025 MRE, not the latest drilling
- Inferred resources are not included in the Base Case mine plan
- Copper is not included in the economic analysis, despite potential
Low confidence — this extraction should be reviewed alongside the original source.
Facts used in scoring: 85
Classification and evidence
Maiden Resourceneutral
First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component.
Why it applies: The PFS establishes a maiden Mineral Reserve for the Luanga Project.
Evidence · text
“Maiden Mineral Reserve Declared”
Proven Reservepositive
Measured Resource with demonstrated economic viability after applying modifying factors.
Why it applies: The PFS declares a Proven Mineral Reserve of 17.7 Mt.

Context: 17.7
Probable Reservepositive
Indicated Resource with demonstrated economic viability after applying modifying factors.
Why it applies: The PFS declares a Probable Mineral Reserve of 69.0 Mt.
Evidence · table
“Probable Reserves”
Context: 69.0
Category Upgradepositive
Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured. De-risking signal.
Why it applies: The PFS reports a reserve conversion ratio of 55% relative to the Measured and Indicated Mineral Resource tonnes and 74% on a PdEq1 metal contained basis, indicating a conversion of resources to reserves.
Evidence · text
“Reserve conversion ratio of 55% relative to the Measured and Indicated Mineral Resource tonnes and 74% on a PdEq1metal contained basis.”
QP/CP Signedpositive
Qualified Person (QP) or Competent Person (CP) named and signed off — a member of a recognized professional association (e.g., AusIMM, SME, AIG, P.Geo) with relevant experience.
Why it applies: The Mineral Reserve Estimates have been prepared by Mr. Porfirio Cabaleiro Rodriguez, an independent QP under NI43-101.
Evidence · text
“The Mineral Reserve Estimates have been prepared by Mr. Porfirio Cabaleiro Rodriguez, B.Sc Min. Eng., FAIG, FAusIMM, director of GE21, an independent QP under NI43-101.”
Cut-off Disclosedpositive
Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.
Why it applies: The Mineral Reserve estimate explicitly states a defined cut-off grade of 0.87 g/t PdEq1.
Evidence · text
“Defined cut-off grade of 0.87 g/t PdEq1.”
NI 43-101 Compliantpositive
Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.
Why it applies: Mineral Reserves are reported in accordance with NI 43-101.
Evidence · text
“Mineral Reserves are reported in accordance with the CIM Standards (2014) and Best Practices Guidelines (2019), as required by National Instrument 43-101 Standards of Disclosure for Mineral Projects (NI 43-101).”
JORC Compliantpositive
Resource estimate prepared in compliance with JORC Code (Australia) — high reporting standard.
Why it applies: Mineral Reserves are reported in accordance with CIM Standards and Best Practices Guidelines, which are CRIRSCO-aligned and consistent with JORC principles.
Evidence · text
“Mineral Reserves are reported in accordance with the CIM Standards (2014) and Best Practices Guidelines (2019), as required by National Instrument 43-101 Standards of Disclosure for Mineral Projects (NI 43-101).”
Inferred Resourcenegative
Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.
Why it applies: The PFS states that no Inferred Resource was counted as Mineral Reserve.
Evidence · text
“No Inferred Resource was counted as Mineral Reserve.”
Stale Estimatenegative
Effective date is >2 years old — data currency concern, may not reflect current geological understanding.
Why it applies: The Mineral Resource estimate underpinning the Mineral Reserve has an effective date of February 18, 2025, which is over a year prior to the PFS announcement date of September 22, 2026.
Evidence · text
“The Mineral Resource estimate underpinning the Mineral Reserve has an effective date of February 18, 2025”
PFS-Supportingneutral
Resource estimate prepared to support a Pre-Feasibility Study — requires adequate M&I component.
Why it applies: The document is a Pre-Feasibility Study for the Luanga Project.
Evidence · text
“Bravo Reports Results of Pre-Feasibility Study for its Luanga Project”
High Recoverypositive
Recovery at or above the exceptional band for the commodity and processing route.
Why it applies: Forecast recoveries for gold (88%) and nickel (70.6%) are particularly high for a flotation circuit, and palladium (81.5%) is also strong.
Evidence · text
“forecast recoveries of 82% Pd, 80% Pt, 55% Rh, 88% Au and 71% Ni”
Recovery Improvingpositive
Recovery improved versus a like-for-like prior test program on the same domain and route.
Why it applies: Metallurgical test work demonstrated improved recoveries for palladium, gold, and nickel compared to the 2025 PEA.
Evidence · text
“Testing on representative Luanga sulphide material demonstrated improved recoveries relative to conventional flotation cells, particularly for palladium, gold and nickel, together with improved selectivity and reduced mass pull as compared to the 2025 PEA.”
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: The Base Case process plant is designed around a flotation concentrator incorporating Jameson Cell flotation technology.
Evidence · text
“flotation concentrator incorporating an updated comminution and Jameson cell flotation circuit”
Multi-Domain Testedpositive
Variability across ore domains (oxide, transition, fresh) has been addressed.
Why it applies: Bravo has undertaken an extensive metallurgical test work program focused on variability.
Evidence · text
“Bravo has undertaken an extensive metallurgical test work program focused on variability”
POX/BIOX Routeneutral
Pressure or bio-oxidation for refractory ore — high CAPEX and OPEX.

How Atlas produces this analysis
Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
