The Tasman Sea is a natural sluice box. Stand on the West Coast after a cyclonic event, and you aren't looking at sand—you're looking at a tactical concentration of minerals.
GEOLOGICAL VECTOR
The gold in these sands has traveled further than any other in New Zealand. release from the Southern Alps, ground by glaciers, and washed through the Buller and Grey river systems, this gold is ultra-refined, ultra-pure, and ultra-thin.
Wave Sorting
High-energy storm surges strip light silica sand, leaving dense layers of magnetite and gold—known to locals as "The Mirror."
Gold Grade
Typically 22k-23k purity. Grain size is "flour" grade, requiring zero-surface-tension recovery methods.
DEPLOYMENT WINDOWS
- The Storm WindowThe 24-hour period immediately following a Tasman gale. This is when the black sand seams are recharged.
- The Neap Tide AdvantageLower water levels expose ancient "beach-lead" gravels that are usually submerged.
- High-Concentrate ZonesFocus on the "Backwash" zones near river mouths like the Waiho and Haast.
TACTICAL EQUIPMENT
Traditional river panning methods will fail. Recovering flour gold requires a specialized protocol.
