By the 80s, a student at the Faculty of me for a month and a half I made ​​a practice Mina Baita Bihor. It was the first time we enter a mine ore until then just practice performing in several coal mine (Jiu Valley) and lignite (Rovinari basin). Baita deposit contains ore complex (Cu, Pb and Zn), wollastonite (chemical formula Ca3 [Si3O9], a rare mineral used mainly in porcelain industry, there are only seven fields in the world, including one from Baita Bihor) molybdenite (chemical standpoint, a molybdenum sulfide, rare mineral used in alloys, especially as solid lubricant in aeronautics). Baita deposit contains: Au, Ag and rare metals (titanium, niobium, tantalum, bismuth, tungsten). On the other side of the mountain (in the same deposit) is found Mina Avram Iancu, where in addition there are large complex mineral ore reserves of uranium and radioactive Pb. Certification of ore exploitation from Baita there since June 2, 1247 in Knights Diploma John, issued by the Hungarian King Bela IV. In reality, the Baita Bihor ore has been mined since the Dacian ("the elderly", as the locals say) the witness stand several galleries, nowadays closed for safety reasons. Through the years '75, exhausting the reservoir formations ("bags") from Baita and topography of the surface is too rough to start prospecting and exploration classical works by drilling, fired erroneously conclude that the deposit is exhausted mine was closed entirely and staff are assigned in other economic areas in the region.
An engineer in the area, arrived in the Ministry of Mines, managed to convince both the minister and Ceausescu, to acquire a US rig latest technology, capable of drilling both vertically, horizontally and diagonally, both top-down and bottom-up. Following the completion of a project, it was decided to continue the digging of galleries dug coast of Gauls and until then inactive. This gallery gallery miners was called "Hope", hoping that they will find ore and mine will reopen. There were four teams digging gallery in four shifts of filing as "tapping" drilling existence or not of the deposit. After digging around 100 meters from the gallery, after drilling performed in the hearth, ceiling and walls of the gallery, they found large reserves of ore, almost inexhaustible. They returned miners and the mine reopened.
