JORC Matamulas

Preliminary Economic Assessment (PEA) for the Mulas Rare Earths Project in Spain in Compilance with the JORC code

- Ongoing


The mine area is a shallow open pit with the minimum impact of active extracting areas and a site reclamation that follows the ore extraction.


Matamulas Project is located within the province of Castilla-La Mancha, in south-central Spain (around 18 km from Valdepeña).

Matamulas Project is a placer project hosting monazite nodules with low thorium and high REO content with low radioactive elements (Th and U).

The project followed the mandatory system for the classification of minerals Exploration Results, Mineral Resources and Ore Reserves according to the levels of confidence in geological knowledge and technical and economic considerations that the JORC Code provides.

The goal under the JORC code was the verification, delimitation and qualification of the resources – reserves. The geological interpretation used in the Mineral Resource estimation is considered robust and representative of the geological knowledge currently available.

Mineral resources are not reserves until they have demonstrated economic viability based on a feasibility study

Impact on the mining value chain

  • EXPLORATION (incl. permitting)
  • EXTRACTION (incl. Permitting)
  • MINE CLOSURE / WASTE management (incl. Permitting)
  • DATA and knowledge base


  • reduced environmental impact


  • increased environmental performance

Mine closure / Waste

  • mine site reclamation/rehabilitation for subsequent uses

Other value chain

EXTRACTION (incl. Permitting)
MINE CLOSURE / WASTE management (incl. Permitting)
DATA and knowledge base


The JORC code is a standardisation of reserves and resource estimation that can be used all around Europe and meets international standards for mining business.

Impact area(s): 

Economic, Employment
Innovation drivers and barriers
Social License to Operate
More transparent policies and promotion of mining and legal security.

Good practice areas

Resource security
Samples from Matamulas contain an exceptionally high relative abundance of Nd, Pr, & Eu oxides. Only with desliming, screening, and gravimetric concentration activities can yield a pure monazite concentrate (approximately 60% TREO by weight) with a very low cost per ore processed ton
