Longonjo Project

Facilitating a greener energy future

Located only 4 kilometres from the modern rail line, leading directly into an Atlantic port, Longonjo leverages excellent transport connections.

The potentially free dig offers a low waste-to-ore ratio, coupled with high-grade surface mineralisation, which together with the favourable location and the transport infrastructure already in place, distinguish Longonjo from the majority of other rare earth projects.

Strategic NdPr Alternative:
the Longonjo Project

Taking advantage of the already well-established infrastructure of Angola, the project site is located mere 4 kilometres from the sealed national highway and rail line that connect the port at Benguela and the provincial capital of Huambo. It’s also in the vicinity of the power transmission line bridging Caala (38km east from the site) and the Luaca Dam interconnecter transmission line.

Why Invest with Us

At Pensana Plc, we are committed to a greener future. Our goal is to provide industries with a low-cost, high-quality, reliable solution to drive the production of greener energy and the electrification of transport around the globe.

The Numbers

International mining industry consultants SRK Consulting has reported an upgraded Measured, Indicated and Inferred Mineral Resource estimate of:

 

313 million tonnes at 1.43% REO including 0.32% NdPr for 4,470,000 tonnes of REO including 990,000 tonnes of NdPr

 

The upgraded estimate:

  • contains more than 2.3 times the previous estimate of the Measured and Indicated resources used in the Preliminary Feasibility Study1 (announced ASX: 15 November 2019).
  • has increased the proportion of the resources reported in the Measured and Indicated categories from 31% to 68%2;
  • and has increased the overall contained NdPr by 35%2;

 

A number of previously announced drill holes in fresh rock mineralisation immediately below the weathered zone have reported continuous mineralisation to a depth of 80 metres, which remain open. Further drilling is planned in this area which will form the basis for future Mineral Resource estimation.

 

At a 0.2% NdPr lower grade cut, the Measured and Indicated Mineral Resource estimate for the Weathered Zone is:

 

39.9 million tonnes at 2.38% REO including 0.52% NdPr for 948,000 tonnes of REO including 208,000 tonnes of NdPr

 

The upgraded resource estimate is being incorporated into the technical studies currently underway and is expected to support an extended mine life on completion of additional workstreams of the Bankable Feasibility Study (BFS).

 

The Weathered Zone is contained within and is a subset of the Total Mineral Resource estimate.

 

1 Comparison of contained NdPr within the Weathered Zone Measured and Indicated categories at a 0.2% NdPr cut off, November 2019 and new Mineral Resource estimates.

2 Comparison of contained NdPr within the November 2019 and new Total Longonjo Mineral Resource estimates at a 0.1% NdPr cut off (Measured+Indicated+Inferred categories).

 

LSE and ASX announcement of 14/09/2020 contain details of the estimation.
