The mine has produced an interesting suite of minerals in recent years, including pale blue to green aquamarine, alpine-like smoky quartz crystals, spessartine, danburite, columbite, cassiterite, helvite, and numerous phosphates including apatite, lithiophilite, purpurite, herderite, strengite, phosphosiderite, hureaulite, robertsite, eosphorite, frondelite and mitridatite (A.
Minerals in the pegmatite are: quartz, microcline, muscovite, albite, amblygonite, "apatite," beryl, uraninite, elbaite, members of the tantalite group, secondary uranium minerals, triphylite, triplite, purpurite, rockbridgeite, tavorite, barbosalite, hureaulite, eosphorite, phosphosiderite, carlhintzeite, colquirite, pachnolite, ralstonite and fluellite.
Valadares, Minas Gerais, Brazil) had about 75 specimens, found last October, of ernstite-coated eosphorite from the Almerino mine, Linopolis, Minas Gerais; they are by far the best yet of this familiar material.

Accompanying minerals such a roscherite and eosphorite are highly characteristic of this occurrence.
Additional minerals present include zircon, gahnite, minor spessartine, hectorite and coronadite, and secondary phosphates fluorapatite, eosphorite and crandallite.
