A matrix specimen with several outstanding yellow crystals of rare Sr mineral strontiojoaquinite on crossite matrix. California field collector & mineral dealer Charles (Chuck) Trantham in the 1970s originally gave this source locality the unofficial name of the "M.T. Jeannes Pit #1". Sometime later (1980s?) an official claim was made of mineral rights with U.S. BLM, and the claimant named this source locality: The Junilla Mine. The old name of this locality on the label likely dates this specimen as found in the 1970s. Ex. William Henderson collection. Ex. Erich Laskowski collection (USA). Mineral
