Asara Resources has reported robust drilling results at its Massan deposit in Guinea, confirming broad gold mineralisation and identifying a new zone 700m south of the core deposit, underpinning plans to grow and upgrade its resource.
- Broad, consistent gold intersections reinforce Massan deposit scale
- New mineralised zone discovered 700m south of core area
- Multiple higher-grade shoots identified along north-south corridor
- Phase 1 and 2 drilling programs advancing resource upgrade and expansion
- Drilling ongoing ahead of August 2026 Mineral Resource Estimate update
Massan Deposit Shows Growing Scale and Continuity
Asara Resources Limited (ASX:AS1) continues to build momentum at its flagship Massan deposit within the Kada Gold Project in Guinea, with the latest assays from 40 drill holes reaffirming broad and consistent gold mineralisation. Highlights include intercepts such as 40m at 0.9 g/t Au and 28m at 1.1 g/t Au, underpinning confidence in the deposit’s continuity and scale. The drilling also delineates multiple higher-grade shoots, adding nuance to the mineralised system along the north-south trend.
These results bolster Asara’s dual strategy: upgrading Inferred resources to Indicated status through deeper and denser drilling, and expanding the Inferred footprint along the 3.5km mineralised corridor. The Phase 1 program focuses on extending the Indicated strike length from around 300m to align with the 1,300m Inferred footprint, while Phase 2 targets systematic infill drilling to firm up the resource classification.
Discovery of New Mineralised Zone 700m South
Perhaps most compelling is the identification of a new mineralised zone approximately 700 metres south of the Massan core, an area previously underexplored. Early results here include 6m at 2.2 g/t Au, featuring a 1m interval at 9.0 g/t Au, and 21m at 0.5 g/t Au with a 3m section at 2.1 g/t Au. While still at an early stage, this discovery signals significant exploration upside beyond the existing resource boundaries, suggesting the Massan system may be more extensive than current models indicate.
Managing Director Matthew Sharples noted the ongoing drilling “reinforces the scale and continued growth of the Massan Deposit,” highlighting the underexplored nature of the broader corridor and the potential for further resource expansion.
Operational Advances and Upcoming Resource Update
Drilling remains active with multiple rigs, three RC, one RC/AC, and one diamond drill, working across the project. Recent equipment upgrades, including new diamond core saws and geotechnical testing tools, enhance on-site geological capabilities and efficiency in core processing. The company aims to complete as many drill holes as possible before an internal cut-off to feed into the updated August 2026 Mineral Resource Estimate (MRE).
Asara’s 2023 MRE reported a total resource of 30.3 million tonnes at 0.95 g/t Au for 923,000 ounces, predominantly shallow oxide and transitional mineralisation. The current drilling campaign is designed to deepen and extend this resource, potentially increasing both the size and confidence of the resource base.
Geological Context and Exploration Potential
The Kada Project sits within the prolific Siguiri Basin, known for orogenic gold deposits, and lies just 36 km south of AngloGold Ashanti’s 10+ million ounce Siguiri mine. The Massan deposit’s mineralisation is structurally controlled, hosted in shear zones with quartz veining and sulphide development, consistent with major regional deposits.
The broad, continuous mineralisation intersected to date, combined with the new southern zone, highlights the under-drilled nature of the corridor and the potential for further discoveries. The company’s systematic approach to drilling density and orientation aims to refine geological models and resource classifications, supporting future development planning.
Bottom Line?
Asara’s expanding footprint at Massan and discovery of new mineralised zones set the stage for a potentially transformative August MRE update.
Questions in the middle?
- Will the new southern mineralised zone significantly increase the overall resource size?
- How will ongoing drilling results influence the conversion rate from Inferred to Indicated resources?
- What impact might deeper drilling and grade shoot delineation have on future mine planning and economics?
