Last month saw Kavango Resources (LSE:KAV) announce the first results of its airborne EM survey to find massive sulphide orebodies in Botswana. The surveying has so far identified 26 conductors along the Kalahari Suture Zone (“KSZ”) for follow up groundwork, exceeding management’s expectations.
Jangada Mines’ (LSE:JAN) flagship asset is the Pedra Branca PGM project in north-eastern Brazil. Pedra Branca is the largest Platinum Group Metals (PGM) project in South America and currently has a JORC compliant resource of approximately 1.45 million ounces of PGM+Au. Today Jangada announced it has updated the process flowsheet for the project with Consulmet Metals (Pty) Ltd and the result is a projected 32% reduction in total capital expenditure. Jangada’s share price was up 5% on the news this morning.
As part of the initial work programme, Consulmet reviewed all metallurgical test work results from the Project and produced a preliminary flowsheet for the production of a PGM-rich nickel-copper sulphide concentrate and a chrome concentrate. Jangada states the review has resulted in important changes to the flowsheet which have simplified and improved the efficiency of the overall process.
The company has continued to deliver positive news on progress at Pedra Branca as it works towards producing a bankable feasibility study (BFS). The current resources are at surface and the study will assume shallow open pit mining and conventional processing methods.
"As we extrapolate the revised capex number into the already robust economic model, the financial merits of Pedra Branca will simply get stronger. Importantly, the revised process flow sheet has demonstrated a simpler and more efficient process route. We anticipate that this will reflect in reduced operating cost metrics that will feed into the ongoing BFS."

Phoenix Global Mining (LSE:PGM) dipped to 30.2p this morning despite recent exploration work indicating a ‘district style’ opportunity at its flagship Empire copper mine in the US.
The firm, which was down 7.2pc as at writing, said it has proven mineralisation along a 3.5km strike within its expanded Empire Mine land position, which now totals 1,837 acres. As a result of the findings, Phoenix will now fast-track further exploration work, with chief executive Dennis Thomas claiming the results suggest a ‘district style’ opportunity:
Oriole Resources (LSE:ORR) is currently sitting at 0.45p after confirming the presence of significant gold anomalism at the Madina Bafé prospect on its Dalafin project in Senegal last week. With the results boosting Madina Bafé’s position as a potential satellite deposit for a nearby gold deposit called Boto, chief executive Tim Livesey talks us through the company’s plans for the project.
