EMERITA REPORTS ALBION PROCESS ACHIEVES 81% GOLD AND 96% SILVER RECOVERY
FROM POST FLOTATION MATERIAL SAMPLES AT IBW PROJECT
TORONTO, March 02, 2026 -- Emerita Resources Corp. (TSX -V: EMO; OTCQX: EMOTF; FSE: LLJA)
(the “Company” or “Emerita”) is pleased to announce results from metallurgical tests using the Albion
hydrometallurgical process and has achieved 81% recovery of gold and 96% recovery of silver at its
wholly-owned Iberian Belt West Project (“IBW” or the “Project”).
These results exceed the previously reported metallurgical results (see press release dated May 27, 2025),
which reported gold recoveries of 81.5% and 64.1% using the optimized CLEVR post-flotation process.
The Albion Process ™ for La Romanera deposit is a post -flotation stage metallurgical process.
Specifically, the samples tested were the residual material remaining after the flotation process removed
the base metal concentrates. Some gold and silver reports to the copper and lead concentrates, however,
more than 80% is in the post flotation material. The Albion Process™ is a commercially proven and widely
implemented technology for the treatment of refractory gold concentrates, based on ultra-fine grinding and
oxidative leaching. The process was developed in 1994 at Core’s laboratories and is licenced worldwide
by Glencore Technology.
Albion Process Results
The Albion Process™ test work was conducted at CORE Resources’ laboratories in Australia. The
Albion-based flowsheet tested consisted of three key steps:
1. Ultrafine grinding and atmospheric oxidation using the Albion Process™
2. Oxidative Neutral leaching within at mildly acidic to near‑neutral pH
3. Precious metals recovery via Carbon-in-Pulp (“CIP”) recovery circuit followed by elution
The Albion Process™ test results achieved:
• 81% gold recovery
• 96% silver recovery
These results demonstrate that the Albion hydrometallurgical oxidation route effectively liberates
precious metals contained within refractory sulphide matrices at the IBW Project and significantly
enhances silver recovery.
Comparison with Pyrometallurgical Oxidation + CLEVR Route
The alternative route previously evaluated for the IBW Project consists of:
1. Single-step pyrolysis and thermal oxidation (pyrometallurgical treatment)
2. Cooling, then acid washing
3. Gold leaching using CLEVR Process™ non-cyanide technology
The CLEVR Process™ test results achieved (refer to press release dated May 27, 2025 for additional
details):
• 81.5% gold recovery
• 64% silver recovery
Table 1 provides a comparison of the post-flotation technologies evaluated by the Company for the IBW
Project.

Silver Recovery 96% 50-64%
Oxidation Type Hydrometallurgical (atmospheric) Pyrometallurgical
Gold Leaching CIP CLEVR (non-cyanide)
Emerita Resources will continue to test several other technologies in 2026 to determine the most optimal
flowsheet for the Project.
The metallurgical results achieved with both pyrometallurgical and hydrometallurgical routes significantly
enhances the technical robustness of the IBW Project. The availability of two technically viable
processing alternatives reduces metallurgical risk and increases flexibility in the selection of the final
process flowsheet. The results offer potential to further optimize the flotation process and base metals
recoveries and is currently being evaluated by the ongoing test work. The Company will decide on one of
these options for the ongoing Prefeasibility Study (PFS), however there will be opportunity to incorporate
further optimization of the process prior to a final design.
Joaquin Merino, P.Geo., President of Emerita, states “The Albion post flotation optimization process for
the IBW Project is a key piece to unlocking the value of the mineralization that we continue to expand
through our drill campaigns. Both technologies that we have examined demonstrate comparable gold
recoveries of approximately 81%. However, the Albion route maximizes silver recovery, which in the
current market may add significant value to the IBW Project. To define the optimal post flotation
processing route to maximize the value of the IBW Project, Emerita is evaluating alternatives not only
based on precious metals recovery, but also with respect to operational efficiency, environmental
performance, scalability and long-term project economics.”
Emerita remains committed to technical excellence and aims to position the IBW Project as a reference
project in the responsible and efficient development of mineral resources.
