Ascendant Resources Confirms Saleable Grade Concentrates Achieved For Copper, Lead And Zinc With Strong Recoveries And Precious Metal Credits At Its Lagoa Salgada Vms Project, Portugal

02.05.2023  |  CNW


• Optimization Tests Continuing for Final Grade and Recovery Profiles

TORONTO, May 2, 2023 - Ascendant Resources Inc. - (TSX: ASND) (OTCQB: ASDRF) (FRA: 2D9) ("Ascendant" or the "Company") is pleased to provide an update of its most recent metallurgical test results as part of its ongoing metallurgical test works which will be included in a Feasibility Study for the Venda Nova deposit at its Lagoa Salgada VMS Project, Portugal, targeted for completion in May 2023.

The Feasibility Program is being led by Quadrante Engenharia e Consultoria, SA. (Portugal) ("Quadrante") with input from Micon International Limited (Canada) ("Micon") who will act as the Qualified Person ("QP") for the 43-101 Resource Update. Soluciones, Concentradores Y Procesos de Ingeniería, S.L. (Spain) ("SCYPI") has managed the flowsheet development and process optimization testing program. Grinding Solutions Limited (UK) ("GSL") has completed the detailed Metallurgical Testing using representative composite samples and variability testing. Maelgwyn Mineral Services Africa (PTY) LTD (South Africa) ("Maelgwyn") is completing independent validation of metallurgical results and completing Locked Cycle Testing (LCT) of selected circuit configurations. Both laboratories are Independent of Ascendant.

The flotation testing and optimization tests will be completed shortly to determine final grade recovery curves for all domains and selection of the optimal grade and recovery for financial analysis. The testing results below are therefore for information purposes only to demonstrate the improvements identified during the Feasibility Study test program compared to the 2021 Preliminary Economic Analysis. The testing results below comprise the Copper, Lead and Zinc grade-recoveries for the Stockwork and Massive Sulphide domains.

Mark Brennan, Executive Chairman, stated, "It is very common for metallurgy in the Iberian pyrite belt to be complex due to the polymetallic nature of the ores, but we are pleased that the metallurgical test work we have completed to date supports our expectations for the Venda Nova deposit and we anticipate these results will support a robust feasibility study. Metallurgical test work to further optimize metal recoveries and concentrate grades will be a continuous process as we develop the project."

Metalurgical Testing

The most recent metallurgical test work was completed by GSL in the United Kingdom and has been validated using Maelgwyn in South Africa. Both laboratories are Independent of Ascendant. These programs were completed using representative core from the 2022 drilling campaign to establish metal recoveries and concentrate grades and complete variability testing. The metallurgical test work results continue to support the use of a planned conventional polymetallic process flowsheet capable of recovering copper, lead, zinc, gold, and silver in three saleable concentrates.

Over the coming weeks the flotation testing and optimization tests will be completed to determine final grade recovery curves for all domains and selection of the optimal grade and recovery for financial analysis. The testing results below are therefore for information purposes only and to demonstrate the improvements identified during the Feasibility Study test program compared to the 2021 Preliminary Economic Analysis. The testing results below comprise the Copper, Lead and Zinc grades-recoveries for the Stockwork and Massive Sulphide domains.

Concentrate Specifications

The metallurgical testing has identified the following saleable concentrate products. These product specifications have been shared with several Smelters and Refineries and confirmed as suitable and meeting their requirements. Final negotiations with smelters and refineries are planned to commence post the publication of the NI 43-101 Feasibility Report. Final grades may change as part of those negotiations.

Massive Sulphides

The Massive Sulphides testing by GSL has developed a sequential flotation circuit producing separate Lead and Zinc Concentrates. The results for the OCT, LCT and Variability tests undertaken by GSL for Lead are summarized below.

The GSL Massive Sulphides testing results for Zinc are summarized below.

The initial indication from the independent verification work by Maelgwyn has shown good alignment on the results achieved. The preliminary results for a Massive Sulphide 7-cycle LCT are presented below.

Note: Results for cycle 7 only, results are preliminary and subject to final confirmation.


The Stockwork testing by GSL has developed a sequential flotation circuit producing separate Copper, Lead and Zinc Concentrates. The Stockwork Open Circuit Tests (OCT), Locked Cycle Tests (LCT) and Variability Tests by GSL for Copper are summarized below.

The Stockwork GSL test results for Lead are summarized below.:

A summary of the Stockwork GSL test results (OCT and LCT) for Zinc is shown below:

Review of Technical Information

The scientific and technical information in this press release has been reviewed and approved by Clinton Swemmer, P.Eng.., Chief Technical Officer, for Ascendant Resources Ltd, who is a non Independent Qualified Person as defined in National Instrument 43-101.

About Ascendant Resources Inc.

Ascendant Resources is a Toronto-based mining company focused on the exploration and development of the highly prospective Lagoa Salgada VMS project located on the prolific Iberian Pyrite Belt in Portugal. The Lagoa Salgada project is a high-grade polymetallic project, demonstrating a typical mineralization endowment of zinc, copper, lead, tin, silver, and gold. Extensive exploration upside potential lies both near deposit and at prospective step-out targets across the large 7,209-hectare property concession.

Located just 80km from Lisbon and surrounded by exceptional infrastructure, Lagoa Salgada offers a low-cost entry to a significant exploration and development opportunity, already showing its mineable scale and cashflow generation potential.

Ascendant currently holds a 50% interest in the Lagoa Salgada project through its position in Redcorp - Empreendimentos Mineiros, Lda, ("Redcorp") and has an earn-in opportunity to increase its interest in the project to 80%. The Company's common shares are principally listed on the Toronto Stock Exchange under the symbol "ASND". For more information on Ascendant, please visit our website at
