More about Steven →

Steven Siemieniuk is an exploration geologist and Professional Geoscientist (P.Geo.) based near Thunder Bay. He spent years prospecting with his grandfather, Dan Calvert, before studying geology, and has since worked across the full exploration cycle in Northwestern Ontario, the Northwest Territories and Nunavut, including Arctic diamond and Cu-Ni-PGE programs. That experience spans greenfield and brownfield exploration: project generation and claim staking, remote and helicopter-supported field programs, deep diamond drilling, program management, Ontario assessment reporting and NI 43-101 technical reporting.

He generated and staked projects later optioned or acquired by TSX Venture and ASX-listed explorers, managed deep drilling for Xstrata Zinc and Glencore at Sturgeon Lake, served as an independent Qualified Person for a TSX Venture issuer, and was project geologist behind Champion Bear Resources' maiden 107,100 oz inferred gold resource at Plomp Farm. In Namibia he did regional compilation and property due diligence near B2Gold's Otjikoto mine, targeting orogenic gold and base metals. His graduate research on GIS-based prospectivity mapping, including a month studying exploration methods at the University of Western Australia in Perth, now drives Exploration Insider's web GIS, remote sensing and machine learning work.

Project generation

Ground that others are still exploring

Projects Steven generated and staked have been optioned or acquired by TSX Venture and ASX-listed explorers, and several are still being explored today.

Gold

Savant Lake Gold Project

Savant Lake-Sturgeon Lake greenstone belt, about 250 km northwest of Thunder Bay. Staked in 2012 by a small vendor group that included Steven, as a target for iron formation-hosted and shear-hosted gold, then carried through prospecting, airborne geophysics, target ranking and drill planning. It has since been optioned or acquired by five public companies and is now a district-scale land position of about 242 km² and the lead exploration priority of Lightning Resource Corp.

  • Generated and staked

    Poisson and McCubbin township claims recorded in June 2012; Steven one of the original vendors.

  • Parkside Resources Corp.

    Optioned the Savant Lake and Wiggle Creek blocks; prospecting returned up to 138.9 g/t Au at the Horseshoe Trench.

  • Independence Gold Corp.

    Assumed the Parkside option and returned the project later that year.

  • New Dimension Resources

    Optioned April 2016; 925 line-km VTEM survey, 104 km² of new staking, five new gold occurrences and Steven's target ranking.

  • Capella Minerals · Prospector Metals

    New Dimension renamed Capella; Prospector Metals earns in toward 70%.

  • Lightning Resource Corp. (TSXV: LTNG)

    Acquires Prospector's Savant interest in September 2026 as its priority project.

VMS Zn-Cu

Sturgeon Lake VMS Project

Mattabi camp, Sturgeon Lake greenstone belt. After years of field and drilling work in the camp for Xstrata Zinc and Glencore, Steven staked and optioned ground beside the camp to ASX-listed Lawson Gold, which became Odin Metals, worked with Glencore toward a joint venture on its Sturgeon Lake properties, and was appointed Odin's Canadian Exploration Manager.

  • Xstrata Zinc and Glencore drilling

    On-site management of deep, geophysically targeted drilling: 5,843 m (2011 to 2012) and 7,683 m in 11 holes (2013).

  • Staked and optioned to Lawson Gold

    Ground beside the camp optioned to the ASX-listed explorer, renamed Odin Metals in November 2017.

  • Canadian Exploration Manager, Odin Metals

    Appointed March 2018: data compilation, 2018 program planning, First Nation consultation and permitting.

  • Glencore farm-out

    Odin signed a C$6.7 million earn-in on Glencore's Sturgeon Lake properties in February 2019.

2017-2018245 km²

Manitou Gold Project
