VANCOUVER, BC / ACCESS Newswire / February 24, 2026 / Kalo Gold Corp. (TSXV:KALO) (the "Company" or "Kalo") is pleased to announce the adoption of the detectORE gold screening system, a field-based geochemical technology developed by Portable PPB Pty Ltd, that is now in routine use at the Vatu Aurum Project, Fiji.
Highlights:
detectORE is now in routine use at Vatu Aurum to provide rapid on-site gold screening of rock, trench, core and soil samples (reported as detectORE Units, "dU").
In an internal 2025 validation study of 824 Vatu Aurum samples, detectORE dU results showed strong linear correlation to certified Fire Assay gold results (Pearson correlation coefficient (R) of 0.98 for total drill core samples; R=0.96 for trench samples).
All detectORE screening data is tracked and QA/QC managed through Portable PPB's pLIMS system, including pXRF calibration verification, reference materials, blanks and duplicates, with batch review and reprocessing where required.
Certified Fire Assay results remain the basis for reportable drill results under NationaI Instrument (NI) 43-101; detectORE screening data may be disclosed as preliminary/supplementary information where clearly identified.
"detectORE has materially improved our on-site workflow due to its linear correlation to certified Fire Assay gold results," stated Terry Tucker, P.Geo., CEO of Kalo Gold. "It allows our team to screen samples on site in real time and prioritize follow-up while certified laboratory assays are pending. The strong correlation we've observed in our internal validation work supports its use as a screening tool, while certified Fire Assay remains the basis for all reportable drill disclosure."
Smarter Exploration with Rapid Gold Data
By deploying detectORE in the field, Kalo can now update geological interpretations more rapidly, allowing for more dynamic and informed drill planning. This is particularly critical at Vatu Aurum, where diatreme-hosted and structurally controlled epithermal gold systems require rapid targeting adjustments. While detectORE is a semi-quantitative screening tool and not a substitute for laboratory assays, it provides the team with useful, rapid geochemical insight.
Technical Notes on detectORE Gold Screening Results
In addition to certified Fire Assay results, this release references gold (Au) values reported in detectORE Units (dU) generated using the detectORE field-based gold analysis system. The Company uses detectORE to provide rapid on-site screening at the Vatu Aurum Project, enabling timely exploration decisions and target vectoring. A dU is a project-specific screening unit representing the leached and collected Au signal measured by the detectORE field procedure. dU values are reported on a ppb-equivalent scale and reflect a semi-quantitative screening estimate; they are not a direct measure of total gold content. Gold values reported in dU are used for vectoring, prioritization, and target refinement. The method uses the proprietary GLIX-20 reagent system to leach gold from fine-grained (pulverized or sieved) exploration samples, with handling, storage, and disposal conducted in accordance with the applicable Safety Data Sheets (SDS) and required PPE. The leached gold is adsorbed onto a proprietary collector device and measured using a calibrated portable X-ray fluorescence analyzer (pXRF) (Evident Vanta, Model V2MR).
Kalo Gold analyzed 824 samples (751 drill core and 73 trench), selected to cover a range of mineralization styles, gold values, and sample conditions encountered at Vatu Aurum to compare dU results against certified Fire Assay. Results showed strong linear correlation (R = Pearson correlation coefficient):
Total Drill Core (751 samples): R = 0.98
Total Trench Samples (73 samples): R = 0.96
Oxidized Samples (364 samples): R = 0.98
Fresh Samples (Unoxidized - 348 samples): R = 0.94
Analysis was performed on pulverized sample splits submitted to Australian Laboratory Services Pty Ltd. ("ALS"), a facility accredited by NATA to ISO/IEC 17025 for certified Fire Assay techniques, enabling direct comparison of dU results to certified Fire Assay values across a range of gold values and sample conditions (0 to >100 g/t Au). Individual samples may show variance due to gold grain size, mineralogy, sulphide content, or oxidation state. Soil dU results have not been directly validated against certified Fire Assay due to shipment/quarantine constraints; interpretation is corroborated by comparisons established from drill core and trench datasets.
Kalo Gold manages its on-site gold screening through a rigorous pLIMS (Portable Laboratory Information Management System) to ensure data integrity:
Automated Tracking: The system monitors sample mass, moisture content, and pXRF calibration in real time.
Verification Tools: Workflows include the use of certified reference materials, blanks, duplicates, and Calibration Collector Devices (CCDs).
Accountability: All results are reviewed by batch; any failure triggers an immediate investigation and sample reprocessing.
dU results are not equivalent to certified Fire Assay results and are not used to estimate Mineral Resources or Mineral Reserves. The detectORE process may not liberate or capture the total gold content present in the sample ahead of the pXRF reading.
Certified Fire Assay results are used for all reportable drill results disclosed under NI 43-101. Where certified Fire Assay results are available for the same sample/interval, the laboratory result is used for reporting. detectORE screening data may be disclosed as preliminary or supplementary information; such results for recently completed drill holes are identified as "certified Fire Assay results pending" and will be updated when laboratory results are received. When both datasets are presented together, they are clearly differentiated by the 'dU' unit designation.
