How It Works
Two transparent pathways to physical gold: choose a Mine Reserve cart with 10,000-BPS published odds, or buy certified, individually photographed slabs directly from our boutique.
Choose a Cart
Sierra operates direct relationships with verified California placer deposits in historic Mother Lode counties. Pick a mine cart starting at $50 with guaranteed minimum gross weights, natural gold purity baselines, and transparent odds.
See your winnings
Every cart unearthing features published 10,000-basis-point mathematical odds. Upon settlement, the depository server assigns an authentic piece and triggers the instant reveal sequence showing gross weight, purity assay, and depository cert serial.
Keep it, sell it, ship it
Every piece you acquire is stored under institutional bailment in insured California depository vaults with $0 ongoing holding fees. You can request insured home delivery straight to your door at any time or trade back for instant Sierra Credit.
Buy Direct Gold Slabs
Prefer direct specimen ownership without a cart draw? Browse our live boutique of individually photographed, sonically sealed California gold slabs. What you see is the exact physical piece allocated to your vault at a transparent fixed price.
