Red-brown microcrystals of ponomarevite, an extremely rare K-Cu chloride from the famous Tolbachik volcano (Tolbachik Volcano, Kamchatka Krai, Russian Federation) the only known locality and associated to green crystals of klyuchevskite. The ponomarevite crystals are difficult to see in the photo. The sample is stored in a closed vial to avoid decomposition in the air atmosphere. Ex Vandenbroucke Museum collection from Waregem, Belgium. Mineral

:Locality: Ojuela Mine, Mapimi, Durango, Mexico Size: 4 × 3.5 × 3 cm Description: In this specimen we can observe a matrix formed by goethite and calcite crystals that are partially covered by kobyashevite, a very rare copper hidroxyl sulphate, with a blue-green color. It is accompanied by small needles of gypsum. In the matrix we can observe some yellowish beudantite crystal aggregates. This specimen has been analyzed. New 2017 find in mina Ojuela.

:Locality: Coal Mine, Mány, Bicske-Zsámbéki Basin, Fejér County, Hungary Size: 2.2 × 0.9 × 0.8 cm Description: Globular agreggate of fibrous kochsandorite crystals in coal from the type locality at Màny in Hungary. The kochsándorite was found in the I/A shaft, formed due to the presence of bauxite (aluminium source) in the coal. This mine was operated from 1988 to 2004. Mineral

Found Sept 2000. Analyzed (EDS). This is one of two specimens with kodamaite from a find of “abundant” varennesite. The other specimen ([1]), has been confirmed by CMN staff via PXRD and EPMA (WDS). At the time that this photo was made (Dec 2017), the pinkish flaky stuff (mostly on the left) was unidentified, so the photo concentrated on the sphalerite crystal. The pinkish flakes have now been identified as likely kodamaite by staff of the Canadian Museum of Nature. (“Likely”, because the description of kodamaite has not yet – Dec 2022 – been published.) Currently the only other photo of kodamaite on Mindat is the one shown in the link given above. So a new photo featuring the kodamaite might be more appropriate. But I no longer own this specimen, so this photo (and the “related” – same minID – photos) will have to do. This specimen was analyzed via “quick & dirty” EDS in Dec 2017. Mineral
