Sovereign AI and Namibian uranium drive small-cap debate

S12 Ep4: The Sunday Roast featuring Luke Sartain, CEO of Narwhal Labs and Rory Harding, CEO of Arkle Resources plc #ARK #CRTM #DNM #OMI #BUCE #ACRM #RCGH #BRES #EPP #ATN #AJAX #GLR #KEN #INC #GDH #EGT #TGR

The episode tests whether ambitious technology infrastructure and early-stage resource exploration can produce credible catalysts in a cautious market.

3 key takeaways
  1. 1Luke Sartain presents Narwhal Labs as a sovereign UK AI utility built around secure communications, automation and infrastructure independence.
  2. 2Rory Harding outlines Arkle Resources’ Namibian uranium programme, where pending assays could determine whether a large footprint becomes a resource.
  3. 3The hosts connect interest rates, inflation and technology sovereignty with a preference for physical assets, energy and selected small-cap opportunities.

Don't miss

Luke Sartain reframes Narwhal Labs from an AI demonstrator into a proposed utility with usage-based pricing and planned satellite infrastructure.

The brief

The hosts open with the week’s AI debate: development slowdowns, Chinese competition, autonomous systems and the risk of building critical infrastructure around uncertain technology.

Luke Sartain argues that Narwhal Labs can offer a sovereign UK AI communications stack, reducing dependence on US frontier-model providers while selling messages, call minutes and automated actions.

Narwhal’s proposed utility model and satellite infrastructure turn the AI discussion into a capital question: can secure, independent capability scale beyond a technology demonstration?

Rory Harding describes Arkle Resources’ uranium exploration in Namibia, where stacked mineralised layers, depth and pending assays will determine whether ULG’s broad footprint supports a meaningful discovery.

The hosts then review small-cap movers, energy and resource investments, interest rates and bonds, ending on a thesis favouring physical assets, energy and technology.
