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 Rare Earths, 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

SRK Consulting, world-renowned international mining industry consultants, have provided us with an inferred Mineral Resource estimate of:


  1. 240 million tonnes at 1.60% REO including 0.35% NdPr for 3,850,000 tonnes of REO including 840,000 tonnes of NdPr.
  2. The updated estimate represents more than a seven-fold increase and contains well over four times the amount of NdPr included in the maiden Mineral Resource Estimate from 26 September 2017.
  3. The NdPr deposit is a blanket of soft weathered material, averaging 30 metres in thickness (up to 75 metres in some locations). The highest grade raw material can be found on the surface, but the deposit remains open at depth and in a number of lateral directions.
  4. Pensana’s initial focus will be on the source occurring within a cut-off of around .65% NdPr. This resource totals 22.9 million tonnes at 4.16% REO and .86% NdPr containing around 953,000 tonnes of REO including 197,000 tonnes of NdPr.
  5. Please refer to tables 1 to 3 for information on the range of cut-off grades, material types and the total rare earth oxide grades.

Due to the high grades on the surface, the weathered zone contains the most favourable NdPr mineralisation for mining and processing. It forms a thick blanket of soft material, extending up to 75 metres in depth in some places. As the near surface, high-grade mineralisation remains open in several directions, this offers the potential for further extensions with additional drilling.
