Joseph Cullen

Joseph Cullen is the CEO, President and a Director of Metalsource Mining (CSE: MSM | OTCQB: MSMMF | FSE: E9Z), the junior explorer advancing the Silver Hill silver-gold project in Davidson County, North Carolina. Silver investors watch Silver Hill because it pairs a historic mining district — which the company describes as the site of America's first silver-producing mine — with one of the more active junior silver drill programs in the United States, including 2026 intercepts such as 434 g/t silver-equivalent over 10.64 metres.

Cullen brings more than 11 years of public-market experience across the resource and technology sectors, focused on investor relations and corporate finance. Before Metalsource, he worked at Deloitte and VMware and co-founded or managed private ventures in financial services, environmental consulting, and technology. As CEO he closed a $6 million private placement in March 2026, added a second drill rig to roughly triple drilling capacity, and expanded the Silver Hill land package to about 1,225 acres across 2.4 kilometres of strike.

His approach at Silver Hill pairs systematic step-out drilling with induced polarization (IP — a geophysical survey that maps sulphide-rich rock) to define targets along the 2.4-kilometre trend. Company-reported 2026 intercepts include 267 g/t silver-equivalent (AgEq — all metals converted to a single silver grade using current prices) over 18.17 metres, and 48.04 g/t gold-equivalent over 12.62 metres that extended mineralization 195 metres down dip, with drilling reaching 335 metres below surface. Reflecting his investor-relations background, Cullen also runs a deliberate market-awareness program around the drill results, appearing in mining media to walk through what each campaign shows.

Silver Hill remains an early-stage exploration project: the grades above are company-reported, equivalent figures use metal prices and historical recovery rates for comparison only, and no resource estimate has been published yet. Following Cullen gives investors a front-row view of how a junior converts a historic district into drill-defined targets — the markers to watch are step-out results, further land consolidation, and the first resource work as the 2026 expansion phase continues.
