• Three targets identified from 3D mapping at Belararox’ Malambo target
  • All targets have porphyry potential
  • Drilling of targets pegged for September this year


Special Report: 3D interpretation of assay results from samples collected at the Malambo prospect, part of Belararox’ Toro-Malambo-Tambo project, have confirmed porphyry-style targets like deposits at globally recognised copper mining operations.

The porphyry potential at Malambo supports Belararox’ (ASX:BRX) recent results at the Toro North target, where rock chip sampling highlighted potential porphyry-style mineralisation with 1.41% copper, 2.49ppm gold and 484ppm silver.

It also matches the porphyry potential discovered at the Tambo South target – all pointing towards similarities with nearby major projects, including  Filo Mining Corp’s C$3.3bn 644Mt Filo Del Sol mine backed by BHP (ASX:BHP), as well as the Los Helados and Potro Cliffs projects being developed by TSE-listed NGEx Minerals.

Surface mapping and analysis support the potential for a large porphyry copper deposit at Malambo across an 800m x 600m area at a depth to ~600m, with both rock chip and talus samples showing the way.

The two sample types serve as inputs into two 3D geochemical models and were collected at intervals of 50-100m in areas where outcrops were found for the rock-chip samples and on slopes near outcrops for the talus samples.


Targets identified

ALS Laboratory provided the results from 248 rock-chip samples and 63 talus samples and three high-priority targets were identified after analysis.

“We‘ve identified significant porphyry targets at Malambo using 3D analysis of rock chip and talus samples which have comparable geochemical signs with the Yerington porphyry copper deposit in Nevada,” BRX MD Arvind Misra says.

“Scores above 0.15 are significant, while those above 0.25 suggest moderate potential for a porphyry centre.

“In practice, and based on the modelling results from porphyry deposits in Ecuador, Chile, Mongolia and elsewhere, probability scores above 0.15 are considered significant, while scores above 0.25 indicate moderate potential for the presence of a prospective porphyry centre.

“At the giant Alpala porphyry copper-gold-silver deposit in Ecuador, a score of 0.25 from surface samples outlined the > 0.5% copper ( and > 0.4 g/t gold) ore zone at depths of >600m beneath surface.”

From collating this information, the BRX team has identified three promising preliminary drill targets based on our interpretation of surface geology and geochemical results.

Regional strength

“We are eager to commence drilling activities in September and are excited about the potential these targets hold,” Misra says.

“With strong copper prices, a prime geological location in a highly prospective area, a friendly jurisdiction, and a top-tier team, Belararox is well-positioned to deliver significant value to our shareholders.

“Our current market cap is around $20m, while neighbouring companies like Filo de Sol ($3 billion market cap with a $100m investment from BHP for a 5% stake) and NGEx (>$1 billion) highlight the potential in this region.”
