Highlander Silver: Comprehensive Geophysical Program Maps Extensive System Concealed by Shallow Cover at Corani
TORONTO, June 25, 2026 (GLOBE NEWSWIRE) -- Highlander Silver Corp. (TSX, NYSE American: HSLV) (“Highlander Silver” or the “Company”) is pleased to report on a comprehensive geophysical study of the Corani Silver Project integrating historical datasets with the first airborne magnetic survey and more extensive induced polarization-resistivity surveys than historically undertaken. The results provide a geophysical signature for the Corani mineral system that is far more extensive than historical drilling coverage, with extensions and untested potential zones to the west and south concealed beneath shallow post-mineral cover.
Daniel Earle, President and CEO of Highlander Silver, commented:
“Highlander Silver has been busy across its portfolio since closing the Bear Creek acquisition in late February. We’re delighted to begin reporting results from Corani that provide an indication of the potential scale of the opportunity we see. Also, we look forward to reporting our first drill results in July. Finally, with strong cash generation and improving performance at our Mercedes operation offsetting spending, the Company has maintained an unaudited cash balance of approximately US$100 million and no debt.”
Highlights
- Completed induced polarization-resistivity and airborne magnetic surveys totaling over 90 km and 600 km, respectively; Defined geophysical signatures of the Corani mineral system through integration with lithology, alteration and resources models, incorporating mapping and core logging datasets; Magnetic lineament analysis highlighted network of north-south and northwest-trending structures interpreted as first order controls on mineralization
- Identified a series of high-priority exploration targets with combined geological, structural and geophysical characteristics analogous to the Corani deposit
- Corani West represents a newly-generated, high-priority target with a large coincident zone of chargeability, resistivity, and magnetic susceptibility consistent with the Corani deposit, concealed under shallow post-mineral cover along a major northwest-trending structure
- Corani East Extension represents the interpreted continuation of the higher-grade Corani East zone south of an eroded block, with historical drilling at the north end of the anomaly partially testing the target, including 42 m at 47.9 g/t Ag from 4m (DDH-C119A)
- Corani South represents a zone of widespread alteration, veining, silicification and hydrothermal brecciation at the intersection of major north-south and northwest trending structures, with significant historical drilling returning robust gold-silver mineralization, including 14 m at 11.7 g/t Au and 48.9 g/t Ag from 32 m (DDH-C52)
- Results support the interpretation that Corani represents a large-scale intermediate sulphidation epithermal system extending well beyond the current resource footprint
- First exploration drilling program in over a decade is now underway with four drill rigs active and first assays expected in July

Technical Information and Quality Control / Quality Assurance
Historical drilling completed by Bear Creek Mining Corporation including drill holes reported here, utilized HQ-diameter diamond core, with reported core recoveries averaging greater than 95%. Bear Creek records reports that drill core was logged and split on site under the supervision of company geologists and sampled on nominal two-metre intervals. Samples were submitted to ALS Chemex Laboratories, an independent laboratory, in Lima, Peru, for analysis. Silver, lead, and zinc assays were determined using multi-acid digestion followed by atomic absorption spectroscopy, while gold analyses were completed by fire assay with atomic absorption finish, with gravimetric determination for samples exceeding 10 g/t Au. Bear Creek's documented QA/QC program included the insertion of certified reference materials at a rate of approximately one standard for every twenty samples.
The assay data associated with the two historical drill holes referenced in this news release were independently reviewed and validated by Highlander. Validation work included verification against original laboratory certificates, physical inspection of drill core stored at Bear Creek's facilities in Juliaca, Peru, and review of the historical digital core photograph archive. This work confirmed the integrity of the reported sampling intervals and the identification of mineralized intervals associated with the significant assay results disclosed herein.
The drone magnetic and induced polarization/resistivity (“IP/Resistivity”) surveys referenced in this news release were subject to quality assurance and quality control review by Dr. Hernan Ugalde, P.Geo., an independent geophysical consultant to Highlander. The review included the ongoing assessment of raw geophysical data as it became available, evaluation of data quality, and consultation with survey contractors to determine the need for reflights and repeat ground survey lines where warranted. The final processed datasets delivered by the geophysical contractors were subsequently reviewed and approved by Dr. Ugalde prior to their use in geological modelling, target generation, and interpretation.
There are no known drilling, sampling, recovery, or other factors that could materially affect the accuracy or reliability of the data referred to herein.
