 Jangada Mines plc ('Jangada' or the 'Company')

High Grade Nickel together with Copper Sulphide and Cobalt Mineralisation Identified

 

Jangada Mines plc, a natural resources company developing South America's largest and most advanced platinum group metals ('PGM') project, is pleased to announce that it has identified significant nickel and copper sulphide anomalies at its Pedra Branca PGM project ('Pedra Branca' or 'the Project') in north-eastern Brazil, which could positively impact its already robust economics.

 

Overview

·     High-grade economic nickel and copper sulphide mineralisation identified immediately beneath the existing PGM and base metal resource

·     Grades include:

2.65% Ni, 0.86% Cu and 0.13% Co over 0.3m at 55m depth

1.65% Ni, 1.5% Cu and 0.1% Co over 1.8m at 47.2m depth

2.30% Ni over 1.0m at 90m depth

1.01% Ni over 1.0m at 84m depth

102 core intersections with nickel grades ranging from 0.5% to 1.0%

·     Newly identified mineralisation, in proximity to the planned PGM open pit operation, could enhance the already strong project economics: potential net present value ('NPV') of US$192 million, Internal Rate of Return ('IRR') of 67% and 1.6-year payback

·     Commissioned independent nickel and copper maiden JORC resource estimate to be published in Q4, 2018

·     Strong market fundamentals for nickel and copper due to decreasing supply and increased demand from new battery technologies

 

Brian McMaster, Chairman of Jangada, said: "The identification of economic grade nickel and copper sulphide immediately beneath the existing PGM resource clearly demonstrates the potential of Pedra Branca to become a pre-eminent global polymetallic operation. 

 

"The nickel price has strong long-term fundamentals and has shown resilience in the recent few months, where commodity prices have been impacted by global politics.  There is growing demand for nickel from the stainless-steel market, and the emerging EV battery sector, and inventories are coming under increasing pressure to satisfy this demand.  

 

"The initial maiden resource estimate that has been commissioned will confirm the current project metrics and scale, in addition to highlighting the potential to expand on the existing base metal resources at the Project.  As shown in the Preliminary Economic Assessment ('PEA') announced in June, our PGM resource already has very robust economics. High-grade nickel, which can be mined from the same shallow open pits as planned for the PGM horizon, is a potential game-changer that could further enhance these economics."

 

Further Information

The occurrence of nickel at the Project has been recorded over several years by various operators.  Its PGM and nickel-copper resources are hosted by a paleo-proterozoic, tabular-shaped ultramafic body known as the Troia Unit; most of the world's high-grade nickel deposits occur in such a geological context.

 

The distribution of anomalous nickel intersections indicate at least five potential targets, all of which are associated with geophysical magnetic anomalies and coincident with the known PGM deposits at the Project. The majority of nickel anomalies currently identified are located in the region of the Cedro, Esbarro and Curiu deposits.  The Company's independent consultants have indicated that there is potential to increase the current nickel resources.

 

A number of high-grade nickel and copper drill hole intersections display the occurrence of massive and disseminated mineralisation at the base of the ultramafic unit, similar to other global nickel deposits. These intersections include the following drill holes:

·     RW014: 2.65% Ni, 0.86% Cu and 0.13% Co over 0.3m at 55m depth;

·     CD50: 1.65% Ni, 1.5% Cu and 0.1% Co over 1.8m at 47.2m depth;

·     PBE05: 2.30% Ni over 1.0m at 90m depth; and

·     PBE11: 1.01% Ni over 1.0m at 84m depth.

 

Additionally, the database contains 102 other drill hole core samples with nickel grades between 0.5%

and 1.0%.

 

Pedra Branca is the largest and most advanced PGM project in South America and currently has a JORC (2012) compliant resource of approximately 1.45 million ounces of PGM+Au at a grade of 1.3g/t PGM+Au (2.5 g/t Pd Eq), 140 million pounds of nickel, 26 million pounds of copper and 6.7 million pounds of cobalt.

 

The Project is located 280 km from the port city of Fortaleza in the northeast of Brazil and holds three mining licenses and 42 exploration licenses over an area of 50,000 hectares.  Previous operators have spent more than $35 million on exploration and development activities, which include 30,000 meters of diamond core drilling, geophysical surveys and metallurgical tests. The current resources are at surface and Jangada is currently preparing a pre-feasibility study assuming shallow open pit mining and conventional processing methods.
