Arquerite is a very rare variety of mercurian silver amalgam containing 13% of mercury. This rarity is found in only 4 localities worldwide, 2 in Chile (Type Locality) and 2 in British Columbia, Canada. This flattened, rounded thumbnail is river-worn, since arquerite is composed of two soft native elements, silver and mercury. The placer deposits here were mined intermittently between 1940 and 1963. Ex. John Saul Collection, a native elements specialist, who obtained this in a trade with Curator Pierre Bariand of the Sorbonne in Paris.
