Southstone Minerals sells 1,043 carats in fiscal Q3

Southstone Minerals Q3 Sales Dip as Diamond Realization Softens Amid Governance Overhang

By The Northwire Desk — AI Analysis May 06, 2026 · 13:12 SML Southstone Minerals Limited
Executive Summary
  • Sales Performance: Southstone reported gross diamond sales of US$2,078,798 for tenders 275 and 276 (March/April 2026) from the Oena mine.
  • Volume & Price: 1,043 carats sold at an average price of $1,993 per carat. This represents a decline in realized price compared to Q2 FY2026 ($2,671/ct).
  • Special Diamonds: High-value stones (>10.8 carats) drove 63% of gross sales value ($1.3M), highlighting reliance on volatile large stone discovery.
  • Revenue Structure: Southstone holds an effective economic interest of only 8.60% in the revenue due to the split between Rietput Delwery BK and African Star Minerals (43% owned by Southstone).
  • Inventory: 590 carats remain unsold pending a May 21, 2026 tender, including eight special diamonds.
  • Operations: Mining continues at the Sandberg S7 Basal section of the Oena mine.
Material Impact
  • Momentum Check: The Q3 sales figure ($2.08M) is significantly lower than the record Q2 FY2026 result ($3.71M), representing a ~44% revenue decline quarter-over-quarter. This breaks the upward trajectory established in early 2026.
  • Price Realization Risk: The average price per carat dropped to $1,993 from $2,671 in Q2 and is approximately 2% below the January 2024 average. This suggests potential grade depletion or market softening for high-value stones.
  • Governance Overhang: The company remains non-compliant with TSX Venture Exchange board composition rules (lack of separate CFO/Independent Director) pending the Afrium uranium transaction closing, which is now extended to September 12, 2026. This regulatory risk persists without resolution in this release.
  • Economic Exposure: Despite headline "sales" figures, Southstone's actual economic capture is limited to an 8.6% effective interest on gross sales. The $2M figure does not translate directly to $2M revenue for the issuer; it implies significantly lower net proceeds relative to the headline volume.
  • Routine Nature: This is a standard operational update confirming continued production, but the deceleration from Q2 highs prevents it from being classified as Material Positive.

Company Overview
  • Flagship Asset: Oena Diamond Mine (Northern Cape Province, South Africa).
  • Project Status: Exploration / Evaluation; technically not yet a producing mine in the traditional sense but generating sales via partnership.
  • Mining Method: Alluvial diamond mining focusing on the Sandberg S7 Basal section.
  • Secondary Assets: Moquita Project (Angola) is terminated; Service Contracts for thermal coal and metallurgical processing are ongoing in South Africa.
