“Star-like sprays of fluorwavellite crystals from the Silver Coin Mine. Although not analyzed for flourine content, it has been noted by Kampf et al. (2017) that: "An extensive EDS survey of wavellites from the Silver Coin mine showed all to be the new species fluorwavellite." Therefore, it is assumed that this specimen also represents that species. Dan A.
