• Four diamond core drill rigs mobilised for accelerated drilling across multiple priority zones
• Targeted infill drilling to improve geological confidence and support conversion to JORC Indicated classification
• Step-out drilling targeting north-west extensions, focusing on continuity of high-grade hinge-zone mineralisation

Sun Silver Limited (ASX: SS1; OTCQX: SSLVF) has commenced its 2026 drill program at the Maverick Silver Project, located in Elko County, Nevada, USA. The program is being executed by experienced Nevada-based contractors and will utilise four diamond core drill rigs to maximise productivity and efficiently advance multiple priority target areas. The 2026 drill program is strategically designed to advance the Maverick Silver Project across three key fronts: Resource Upgrade - Targeted infill drilling within the existing Mineral Resource to improve geological confidence and support conversion to JORC Indicated resource classification; Resource Growth - Step-out drilling targeting north-west extensions, focusing on continuity of the high-grade hinge zone mineralisation; and Metallurgical Advancement - Collection of additional diamond core samples for metallurgical test work to support future development and processing studies. The program will focus on priority zones within and adjacent to the existing Mineral Resource, including infill areas targeting improved resource confidence and classification upgrade, north-west extension zones targeting continuation of high-grade mineralisation, and near-surface mineralisation supporting potential from / near surface development optionality. 2026 represents a critical phase in advancing the Maverick Silver Project toward development, with key activities including advancing Mineral Resource classification toward JORC Indicated classification, further expansion of the Mineral Resource through targeted step-out drilling, further advancing metallurgical understanding to support heap leach processing pathways, generating technical inputs for future development studies and mine planning, progressing environmental permitting and baseline studies, ongoing mine planning activities, and targeting completion of a Scoping Study in Q4 2026 and a Pre-Feasibility Study in Q2 2027.

The 2026 drill program accelerates Maverick on multiple fronts including resource upgrade, growth and development readiness. With four rigs turning, Sun Silver is advancing toward a JORC Indicated Mineral Resource while expanding the system, alongside delivering key metallurgical inputs. In parallel, the company is progressing mine and processing permitting and advancing development studies, positioning the Maverick Silver Project as a leading U.S. silver project.
