Tomkap Tourmaline Mine

The Yinnietharra Dravite deposit sits within the Gascoyne region of Western Australia, characterised by semi-arid, low-relief plateau terrain dissected by ephemeral creek systems. The shallow regolith profile and lateritic surface cover directly condition mass earthmoving scope, limiting heavy machinery deployment. Selective manual excavation dominates due to fragile gem-bearing host rock. Seasonal flooding of the Gascoyne River catchment imposes strict operational windows, compressing productive campaign periods to dry-season schedules.

Originally exploited by A. Soklich (1968–1971), the lease was acquired in 2010 by Tom Kapitany and rebranded as Tomkap Tourmaline Mine. The operation follows a small-scale, campaign-based model rather than continuous production. Key B2B considerations include:

• FIFO/DIDO roster constraints due to extreme remoteness (~250 km from Carnarvon)
• No permanent on-site workforce infrastructure confirmed
• Gem material commercialised via Crystal World Australia's direct retail and wholesale channels
• Lease status: Operating under WA Department of Mines tenement framework

The mineralisation targets dravite tourmaline (magnesium-rich end-member) hosted in Proterozoic metamorphic sequences. Extraction methodology is artisanal-selective, with no conventional primary crushing or flotation circuit deployed. Key engineering parameters:

• Hand-sorting and manual disaggregation of pegmatitic/metamorphic host matrix
• No milling or chemical beneficiation reported
• Water supply logistics critical given arid site conditions
• Gem recovery prioritises crystal integrity over volumetric throughput

As a small-scale gem operation, formal ESG reporting frameworks are not publicly documented. However, WA Mining Act obligations apply to tenement rehabilitation. Sustainability considerations include:

• Minimal tailings generation — no processing residues from chemical circuits
• Low surface disturbance footprint relative to bulk commodity operations
• Rehabilitation liability managed under DMP WA tenement conditions
• Provenance traceability via Crystal World Australia supports ethical gem supply chain positioning
