Anna adit, Mitterberg District, Mühlbach am Hochkönig, St Johann im Pongau, Salzburg, Austria

(Annastollen, Revier Mitterberg, Mühlbach am Hochkönig, St Johann im Pongau, Salzburg, Österreich)

In the side veins worked by the Anna edit, concentric layered pitchblende nodules to a diameter of several cm, including a suite of sulphides in microscopic quantities, occurred abundantly in vugs of the vein carbonates. Within the Mitterberg district, this type of mineralization - also known as 'UKP' (Uranknollen-Paragenese = uranium nodule paragenesis) - was almost exclusively restricted to this locality. Uranium minerals recovered from other sections are typical secondary formations, deposited by circulating groundwaters. Located about 2.5 km NE of Mitterberg mountain, in the northeastern Dienten Mts.
