AI opinion on approximate gem value12 May 2025 13:14
For the dinosaurs in here I again lend my younger but not young skills in navigating the premium AI I pay for, here is what the AI thinks - don't shoot the messenger, take it as free information and do with it what you will. I wish I saw the interview sooner!
Absolutely — let’s break this down step by step and try to derive a rough valuation range for the historical diamond parcel using the figures Andrew provides, combined with market data on diamond pricing.
---
Key Information from Andrew (CEO):
Total carats: ~130,000 carats
Stones: ~25,000 individual stones
Average stone size: 5–9 carats (unusually large for alluvial diamonds)
% gem-quality diamonds (pre-cleaning visual estimate): ~27% (normally 10–15%)
% industrial/low-grade: ~73%
Presence of "specials" (11–40 carats): Yes, significant quantity
Still uncleaned: True value not fully realized yet; cleaning may reveal better clarity/color

Step 1: Estimate Carats by Quality Type
Gem-quality:
27% of 130,000 carats = 35,100 carats
Industrial/near-gem:
73% = 94,900 carats
---
Step 2: Price Assumptions (based on market data):
Diamond prices can vary wildly depending on quality, cut, and color. However, for a rough calculation:
Industrial diamonds: $1–$10 per carat (used in abrasives, not jewellery)
We'll conservatively use $5/carats
Gem-quality diamonds:
Can vary from $500 to over $10,000 per carat
For uncut, mixed-quality stones, a conservative rough average is $500–$1,000 per carat
For large "specials" (11+ carats), the price can spike significantly, sometimes $3,000–$5,000 per carat or more — but we’ll bake this into the upper estimate later.

Step 3: Base Valuation Calculations
Low-end estimate:
Gem-quality: 35,100 × $500 = $17,550,000
Industrial: 94,900 × $5 = $474,500
Total low-end value: ≈ $18 million
Mid-range estimate:
Gem-quality: 35,100 × $1,000 = $35,100,000
Industrial: 94,900 × $5 = $474,500
Total mid-range value: ≈ $35.6 million
High-end speculative estimate (assuming higher portion of gem-quality cleans up better, large specials, favorable market conditions):
Assume 35,100 carats gem split:
25,000 carats @ $1,000 = $25M
10,100 carats (specials and larger stones) @ $3,000 = $30.3M
Industrial: 94,900 × $5 = $474,500
Total high-end: ≈ $55.7 million

Step 4: Comparison to Market Cap
Vast Resources current market cap (at 0.51p/share) = £14M, or roughly $17.5M USD
So:
Low-end diamond valuation = ~1× market cap
Mid-range = ~2× market cap
High-end = ~3–4× market cap
This aligns exactly with Andrew’s statement: “many multiples of our market cap a few weeks ago.” (when the company was valued closer to £4-6M).

Other Considerations:
Cleaning costs: Likely significant, especially with their multi-stage acid boiling process
Cutting & polishing: Could
