ABRASILVER COMMENCES PHASE VI DRILL PROGRAM AT DIABLILLOS AND REPORTS ASSAY RESULTS
Abrasilver Resource Corp. has commenced the phase VI diamond drilling program at its wholly owned Diablillos project in Argentina, together with additional assay results from the recently completed phase V drill program.
Phase VI drill program highlights
- Fully financed 15,000-metre phase VI diamond drilling program is designed to expand and upgrade the existing mineral resources and evaluate high-priority exploration targets;
- Primary focus on extending gold and silver mineralization beyond current conceptual open pit limits at Oculto East, Oculto Northeast, Cerro Bayo and JAC;
- Targeted drilling also planned to assess sulphide-hosted and porphyry-style mineralization at Oculto Deep and Cerro Viejo;
- Phase VI results are expected to support continued mineral resource growth beyond those included in the upcoming definitive feasibility study, which remains on schedule for release in Q2 2026 and will incorporate all data from the recently completed phase V program.
John Miniotis, president and chief executive officer, commented: "The successful completion of our phase V drilling marks another important milestone for Diablillos. Phase V drill results will be incorporated into an updated mineral resource estimate (MRE) that will form the basis of the upcoming definitive feasibility study (DFS). With phase VI now under way, our exploration focus remains on unlocking additional upside beyond the DFS."
Dave O'Connor, chief geologist, commented: "Phase V delivered impressive intervals of gold mineralization extending beyond the conceptual open pit limits at Oculto East, underscoring the strength, continuity and scale of the Diablillos mineralizing system. Phase VI has been carefully designed to build on this success -- expanding known mineralized zones, upgrading mineral resources within and beyond the existing open pit, and testing several high-priority exploration targets across the district."
Phase VI program overview
The phase VI drill program is expected to comprise approximately 15,000 metres across approximately 50 diamond drill holes. Drilling activities have now commenced with two drill rigs active, and the program expected to be completed before year-end.
Drilling is designed to both expand and upgrade mineral resources within and beyond existing conceptual open pit limits, as well as to test high-priority exploration targets across the broader Diablillos district. The highest-priority targets are focused on extending oxide gold and silver mineralization at Oculto East, Oculto Northeast and Cerro Bayo, where recent drilling demonstrated strong continuity and potential to further expand open pit mineral resources and improve strip ratios.
The phase VI program also includes drilling to evaluate the Condoryacu target, which represents a new exploration area where the company has recently entered into an option agreement to acquire the property from a third party vendor. Condoryacu is located approximately three kilometres south of the latest conceptual Oculto open pit and has not previously been drill tested by the company. Initial drilling will focus on verifying historical exploration data, and assessing the continuity, geometry and scale of the mineralization. Successful results from this work could support the exercise of the option and highlight the potential for additional satellite mineralization within the broader Diablillos district.
Phase VI drilling will also focus on JAC, Sombra and Fantasma, where additional drilling is designed to test for extensions of known mineralization and assess continuity between deposits. Collectively, the phase VI program is expected to support continued mineral resource growth and longer-term exploration upside beyond the DFS.
Latest phase V drill results
As part of the recently completed phase V drill program, the company has received additional assay results from drilling at JAC, which will be incorporated into the upcoming MRE. Recent drilling at JAC was primarily aimed at delineating the margins of known mineralization. Results confirm that silver mineralization remains present at the periphery of the deposit, although grades decrease as the company drills further away from the higher-grade core. The latest results are summarized in Table 1.
About Diablillos
The Diablillos property is located within the Puna region of Argentina, in the southern part of Salta province along the border with Catamarca province, approximately 160 km southwest of the city of Salta and 375 km northwest of the city of Catamarca. Abrasilver acquired the property in 2016, which comprises 15 contiguous and overlapping mineral concessions with excellent year-round road access.
Exploration to date has outlined multiple occurrences of silver-gold oxide mineralization at Oculto, JAC, Laderas and Fantasma, located within a 500 m to 1.5 km distance surrounding the Oculto/JAC epicentre. To date, over 150,000 metres have been drilled on the property, which continues to demonstrate the strong growth potential of shallow, oxide-hosted silver and gold resources. In addition, a large porphyry complex is centred approximately four kilometres northeast of Oculto which includes outcropping porphyry intrusions within a major zone of alteration and associated gold-rich epithermal mineralization.
Comparatively nearby examples of high sulphidation epithermal deposits include: La Coipa (Chile); Yanacocha (Peru); El Indio (Chile); Lagunas Nortes/Alto Chicama (Peru) Veladero (Argentina); and Filo del Sol (Argentina). The most recent mineral resource estimate for Diablillos is shown in Table 2.
QA/QC (quality assurance/quality control) and core sampling protocols
Abrasilver applies industry standard exploration methodologies and techniques, and all drill core samples are collected under the supervision of the company's geologists in accordance with industry best practices. Drill core is transported from the drill platform to the logging facility where drill data is compared and verified with the core in the trays. Thereafter, it is logged, photographed and split by diamond saw prior to being sampled. Samples are then bagged, and quality control materials are inserted at regular intervals at site; these include blanks and certified reference materials as well as duplicate core samples which are collected in order to assess sampling precision and reproducibility. Groups of samples are then placed in large bags which are sealed with numbered tags in order to maintain a chain-of-custody during the transport of the samples from the project site to the laboratory.
All samples are received by the ASA (Alex Stewart Argentina) preparation laboratory in Salta, where they are prepared, then the pulp sachet is directly dispatched to its facility in Mendoza, Argentina, where they are analyzed. All samples are analyzed using a multielement technique consisting of a four-acid digestion followed by ICP/AES detection, and gold is analyzed by 50-gram fire assay with an AAS finish. Silver results greater than 100 g/t are reanalyzed using four acid digestion with an ore grade AAS finish.
