Great Pacific Gold Corp. initiated drilling at Kavasuki in February 2026 and to-date the Company has completed five diamond drill holes with 688 meters drilled. Holes one, three and four have been previously released with Hole 5 results have just been received.
A sixth hole is underway.

KVH-05: 29.5 meters @ 0.45 g/t AuEq from 15.2 m (0.38 g/t Au, 3.43 g/t Ag, 0.02% Cu).
KVH-06: underway and nearing completion with a step-out of 50 meters west from KVH-05. Additional six drill holes totalling approximately 900 meters planned to test Kavasuki along 500 meters of north-south strike length. Drilling is planned to be completed by the end of June 2026.
Results from KVH-05 confirm the continuation of quartz?carbonate veining, silicification, hydrothermal brecciation and gold mineralization within the Kavasuki system, although grades are lower than those returned in KVH-03 and KVH-04. When integrated with earlier drilling, the results support the interpretation of a broad, structurally controlled hydrothermal system in which higher-grade mineralization is likely focused within discrete structural positions. KVH-05 returned broad lower-grade mineralization, but importantly, it also intersected the same style of quartz?carbonate veining, silicification and hydrothermal brecciation observed in earlier holes.
This supports our interpretation that Kavasuki is a broad hydrothermal system, with higher grade, structurally controlled lenses within a broader lower grade mineralized envelope. A key objective of the current program is to resolve the geological and structural framework at Kavasuki, which has not previously been systematically defined. The drilling completed to date is improving our understanding of vein orientation, continuity, fault controls and the likely positions of higher-grade mineralization.
When KVH-05 is viewed alongside KVH-03 and KVH-04, the results continue to support a coherent mineralized system with clear indications of scale. Our strategy is to determine the lateral and depth extents of the system which will simultaneously be testing the chargeability anomaly before moving along strike to test the broader chargeability anomaly and corridor. The Wild Dog Project hosts a 15-kilometre-long structurally controlled mineral corridor containing multiple epithermal gold targets and porphyry copper-gold potential identified through recent MobileMT geophysical surveys.
The corridor contains the Sinivit-Kavasuki vein system and multiple advanced targets including Kasie Ridge, which are now being systematically drill-tested as part of the Company?s 2026 exploration program. Insert map shows the position of the Sinivit?Kavasuki system within the broader corridor and target pipeline. KVH-05 Drilling Update Drill hole KVH-05 was designed to test the down-dip extension of mineralization intersected in KVH-04 and to improve the Company?s understanding of the continuity, geometry and variability of the main Kavasuki vein system.
KVH-05 intersected significant quartz?carbonate veining, silicification and hydrothermal brecciation, consistent with the alteration and veining styles observed in earlier Kavasuki holes. Assay results returned broad low-grade mineralization, including 29.50 meters @ 0.45 g/t AuEq from 15.20 meters. Results from the second half of the hole are still pending.
KVH-06 ? Current Drilling to Resolve Structure and Depth Potential Drill hole KVH-06 is currently in progress and has reached approximately 90 meters downhole. The hole is designed to follow up on observations from KVH-05 and further refine the geological and structural interpretation of the Kavasuki system.
Key objectives include assessing lateral continuity of mineralisation, evaluating grade variability, and testing the presence and influence of potential flat-lying structures and their relationship to mineralisation. Drilling progress has been impacted in the past few weeks due to adverse weather conditions associated with Tropical Cyclone Maila, which tracked through the Solomon Sea during April. The system brought significantly elevated rainfall across Papua New Guinea, resulting in access constraints, track deterioration, and reduced drilling efficiency during this period.
KVH-07 ? Testing Western Extents and Intrusive-Related Controls Drill hole KVH-07 has been designed as a step-out hole to test the western extents of the Kavasuki system and evaluate whether veining and silicification continue beyond the area of current drilling. The hole is planned to assess mineralization beneath a newly identified intrusive sill and determine whether the main mineralized structure continues through, is offset by, or is locally influenced by this intrusive body.
KVH-07 is an important step in evaluating the lateral extent of the Kavasuki system and testing whether mineralization continues across different structural and lithological domains. Results from this hole will assist in determining whether the system can be expanded westward and whether additional structural positions may host higher-grade mineralization. Updated Targeting and Drilling Strategy The Company?s updated drilling strategy at Kavasuki is focused on resolving the geometry, scale and structural controls of the mineralized system before wider step-out drilling is undertaken.
Recent drilling has improved confidence that the main vein system dips to the northwest, with mineralization occurring within a broader zone of silicification, veining and hydrothermal brecciation. This improved understanding has resulted in a refinement of drill orientations and hole placement to better test the interpreted geometry of the system. The updated targeting model also incorporates geophysical and geochemical data, including a broad chargeability anomaly at Kavasuki and historic surface trenching that identified gold anomalism to the northwest of current drilling.
