Investigator Silver Ltd (ASX:IVR, OTC:SUTAF, FRA:VOP) has strengthened its executive and project delivery capability as it moves the Paris Silver Project in South Australia toward development, following completion of a Definitive Feasibility Study (DFS) that confirmed a clear pathway for the project.
The DFS confirmed Paris as a robust and financeable silver development project capable of producing more than 30 million ounces of silver over an initial 11-year mine life.
With parallel workstreams underway across permitting, detailed engineering, execution readiness, financing and resource growth, Investigator has added senior personnel with mine development, construction and operational experience.
Building the team to deliver Paris
Key appointments include Joe Sutanto as chief financial officer and joint company secretary, effective September 7, 2026.
Sutanto brings more than 20 years’ experience across accounting, commodity trading, corporate finance, governance, project development and mining operations.
He joins after serving as chief financial officer and company secretary of Hillgrove Resources, where he worked with Investigator managing director Lachlan Wallace through the financing, development and commissioning of the Kanmantoo Underground Copper Mine in South Australia.
Investigator has also appointed Milan Jiranek as project director for construction. Jiranek has experience delivering mining and processing infrastructure, including developments across Peak Iron’s Gawler Craton operations, and will lead detailed engineering and execution planning, including EPCM activities.
Former OZ Minerals project director Geoff Deans has joined as project director for technical workstreams, bringing major project delivery experience including the Carrapateena block cave expansion. His work will focus on approvals, permitting, native title, stakeholder engagement and technical integration.
Luke Cerny has been appointed principal mining engineer, with experience spanning mine development and operations, including Kanmantoo and Ok Tedi Mining Limited.
Dr Ben Cave has joined as senior exploration geologist from IGO Limited (ASX:IGO) and will support ongoing exploration across the Paris Silver Corridor and broader regional opportunities.
“Significant scale and quality”
Investigator managing director Lachlan Wallace said the appointments reflected a deliberate strategy to strengthen the company’s project delivery capacity.
“The Paris Definitive Feasibility Study confirmed a project of significant scale and quality. As we progress permitting, detailed engineering, financing and resource growth activities in parallel, it is important that we continue building the capability required to successfully develop and operate the project.
“These appointments complement the existing technical team that successfully advanced the Paris Project through the Definitive Feasibility Study and reflect a deliberate strategy to strengthen the Company's capability across project delivery, finance, engineering, operational readiness and mine operations.
“Collectively, the team now includes individuals who have played leading roles in the financing, development, construction and operation of projects including Kanmantoo, Carrapateena and Peak Iron's Gawler Craton operations.
“Importantly, many of these individuals have recent and highly relevant South Australian mine development experience. They understand the local operating environment, contractors, infrastructure, regulatory framework and the practical realities of delivering projects in this State.
“Combined with the extensive knowledge held within Investigator's existing technical team, this capability significantly strengthens our ability to advance the Paris Silver Project toward development and unlock value for shareholders.”
Paris workstreams advance
Investigator is well funded to advance Paris, with about A$60 million in cash supporting workstreams required ahead of a final investment decision.
Current activities include progressing permitting and approvals, advancing detailed engineering and execution readiness, continuing project financing and strategic engagement, and ongoing drilling and optimisation programs aimed at expanding the Paris pit and enhancing project value.
About Investigator Silver
Investigator Silver’s 100%-owned Paris Silver Project is about 70 kilometres north of Kimba on South Australia’s Eyre Peninsula.
The project hosts a JORC 2012 Mineral Resource of 24 million tonnes at 73 g/t silver and 0.41% lead for 57 million ounces of silver and 99,000 tonnes of lead.
Paris is a shallow, high-grade silver deposit considered amenable to open pit mining, giving Investigator exposure to silver demand across industrial, renewable energy and manufacturing applications.
The project also has a 2026 Ore Reserve Estimate of 12 million tonnes at 88 g/t silver for 33 million ounces of silver.
