The mineral resources and reserves of the company form the basis for Viscaria’s future operations. By carefully planning how the operations will be conducted and with a deep understanding of the characteristics of the minerals, we can make well-founded investment decisions.
Through extensive exploration work, Viscaria’s team is constantly increasing its knowledge of our deposits. Exploration work focuses on both identifying new deposits and deepening our understanding of already known mineralisations.
Since the acquisition of Viscaria in 2019, we have continuously prospected in the area, leading to even better opportunities for future mining operations. In 2023, our drilling activities intensified to improve the precision in assessing mineral grades and the appearance and nature of mineralisations.
Currently, our main focus is on prospecting in the Viscaria area, but also within the project in Arvidsjaur. We look forward to continuing the work to initiate mining operations that will contribute to a sustainable and successful copper supply.
Mineral Resources
Mineral Resources represent a concentration or occurrence of minerals in or on the Earth’s crust that have reasonable prospects for economic extraction. To assess a mineral resource, geological properties such as geometry, density, quantity, grade, and other geological characteristics are evaluated.
Mineral Resources are classified according to the degree of knowledge about the mineralisation into three categories: inferred, indicated, and measured, with “measured” representing the highest degree of confidence.
Mineral Reserves
Mineral Reserves are the portion of known and/or indicated mineral resources that are deemed economically viable to extract. When assessing Mineral Reserves, we consider factors such as the proportion of waste rock and potential losses during mining or extraction. These assessments are conducted through studies that include so-called modifying factors, which demonstrate whether extraction is justifiable at the time of reporting.
Mineral Reserves can be classified into two categories based on the level of certainty: “probable reserves” and “proven reserves,” with “proven” being the highest category.
At Viscaria, we continuously work to meticulously examine and evaluate our Mineral Resources and Mineral Reserves. This is crucial for our operations to ensure a sustainable and profitable mining business.
Mineral Resources (May 2025)
In May 2025, Viscaria presented a resource update of the company’s mineral assets. The report is in accordance with the PERC Standard. According to the May 2025 update, the copper-bearing rock resources in the Viscaria area amount to 108 million tonnes, with an average copper grade of 0.9 percent.
Reporting according to the PERC standard
Viscaria follows the recommendations of the industry organisation Svemin when reporting exploration results, Mineral Resources, and Mineral Reserves. Svemin prescribes the use of internationally recognised standards and particularly recommends the PERC Standard, which is based on The Template developed by CRIRSCO.
Viscaria’s Mineral Resources and Mineral Reserves are in accordance to PERC Standard 2021, the latest issued standard.
”It’s crucial for us to assess the size and grade of our deposits in a systematic and transparent way. Quality defines everything we do, from exploration to reporting, which is why it is natural for us to use the latest PERC standard, which sets high demands on the reporting of our assets.
We meet industry standards and continuously improve our processes to deliver the best possible results.”
Ross Armstrong, Viscaria’s Head of Geology
