Strategic Minerals for new economies

Strategic Minerals Europe produces various mineral concentrates, currently tin, tantalum and niobium. These products are essential for everyday use: in the technology industry (microprocessors, computers, mobile phones, satellite manufacturing), in the health industry (medical equipment or implants) or even industrial products for the glass industry, superalloys with a lower CO2 footprint and the manufacture of refractory paints.

In the future, the company will seek to produce other metallic minerals such as lithium and industrial minerals such as quartz, feldspar, mica and kaolin will also be extracted.

These are high quality very scarce products, of great economic importance, all of which are mined in conflict-free areas.

We are the largest producer of tin and tantalum in the European Union

Products under development

The principles of the circular economy that govern the Penouta Mine project allow Strategic Minerals Europe to promote continuous development to maximise the use of the resources extracted, optimising the extraction process and minimising the effects derived from its activity.

Mina de Penouta

A benchmark in the recovery of raw materials

The Penouta Sn, Ta and Nb mine is located in the municipality of Viana do Bolo, on the central-eastern edge of the province of Ourense, and is currently the only tantalum and niobium mine in production in Europe.

Strategic Minerals Spain is currently operating the project of this mining site from which it extracts tin, tantalum and niobium, the latter two elements are used to make columbite-tantalite and other mineral aggregations, with tantalum and niobium being considered strategic elements and tin considered a necessary mineral for the energy transition by the European Union due to its scarcity and its important properties for the manufacture of technological components.

The Penouta Mine project:

The Company will continue to exploit the mineral resources that were certified by SRK in NI 43-101 for 30 years, renewable for up to 7. Allowing the Company to fully develop the open pit mine to exploit cassiterite (tin), tantalum and niobium, and also allowing the exploitation of the industrial minerals that exist in the mine, such as quartz, feldspars and micas.

Penouta Mine initially began with the use of the tailings from the old exploitation within the framework of circular economy and environmental sustainability. The company will maintain its commitment to the circular economy by revaluing the future tailings produced by the mine.

The Penouta Mine is located in a conflict-free zone, in line with both the company’s policy in the mineral extraction process and with European and international policies in this respect, making it a European mine of strategic importance.

An historic project

  1. 1906

    The first declaration registered at the Jefatura de Minas was located, corresponding to the Olga mine, no. 1229, with 64 holdings.

  2. 1965

    Work began to deepen the excavation, as it was found that the rock underneath the overburden was mineralised.

  3. 1968

    The "Project to measure and evaluate tin reserves in an area of the Penouta mining group (Ourense)" was carried out by the Spanish Geological and Mining Institute.

  4. 1970

    Exploitation of some 700,000 t of kaolinised leucogranite.

  5. 1985

    Mine operations ceased.

  6. 2011

    Start of geological research work at the site.

  7. 2014

    Project feasibility pre-operational and environmental studies carried out.

  8. 2017

    Strategic Minerals Spain starts the operations for exploitation of the mine as a model for modern, responsible and sustainable mining.

  9. 2021

    Research phase commences through the authorised pilot front.

  10. 2022

    The company has been awarded the open pit concession for 30 years, renewable for up to 75 years.

    Mina de Penouta


Strategic Minerals Spain has four projects in Galicia: Penouta Mine, Alberta II, Carlota and Macarena.

Penouta Mine

It covers 282 hectares.  The mineral resources were exploited from the beginning of the 20th century until the 1980s, with research being reactivated in 2011 by Strategic Minerals Spain. It has certified resources of more than 76 million tonnes measured and indicated according to NI 43-101. The certification was carried out by SRK Consulting.

Tabla Mina

Alberta II

It covers 1,015 hectares. The “Alberta II” research licence is located in the province of Ourense (Galicia), within the Ribeiro region in western Ourense, in the municipality of Avión. In the first stage, 40% of the deposit was explored. 12 Mt of inferred resources, certified by RDA. Increasing potential to find subsurface veins containing lithium mineralisation according to the 2018 exploration campaign.


It covers 2,670 hectares. The exploration will be carried out in later stages. The deposit consists of pegmatite bodies containing Tin (Sn), Tantalum (Ta), Niobium (Nb) and Lithium (Li), similar to Alberta II.


It covers 1,830 hectares. Exploration work will be carried out in future stages with mineralised quartz veins and granite hosted with high Tin (Sn) and Wolfram (W) content.

What we do


Strategic Minerals Europe defends human rights, as well as the exploitation of minerals in an ethical and responsible manner, sanctioning the extraction and purchase of these materials in conflict zones, as defined by the Organisation for Economic Co-operation and Development (OECD).

All its products come from the mining operations owned by the company in Spain, and are therefore from conflict-free zones. In addition, they have high added value, given the very low primary production of these minerals in Europe, reducing dependence on imports from third countries, including conflict zones, making them a valuable solution for new economies.

Strategic Minerals has a conflict minerals policy in line with the international recommendations of the OECD and Regulation (EU) 2017/821 of the European Parliament and of the Council of 17 May 2017 in this regard.

Our minerals are a value solution for new economies
