Former village Jelení (earlier Hirschenstand) was founded as a mining settlement of Thuringia and Saxon colonists. Even long time before that (perhaps since the 12th century), tin grits were washed from sediments of the Slatina Creek and its tributaries. Sometime in the 15th century mining of primary ore was added to panning. The biggest mining boom had began in the second half of the 16th century, as evidenced by entries in the preserved Nejdek Mining Book. Placers and mines did vanish even during the Thirty Years War, when the Protestant exiles were quickly replaced by the new mining entrepreneurs. When Count Czernin bought Nejdek estate in 1633, the purchase contract listed tin mines as a particularly important item.
A striking monument of the tin ore mining is the district Jelení hlava (Hirschkopf), which is located on the slopes of the hill U Štoly (941.3 m), a forested rise southeast of Jelení, lifting steeply above the river bed of the Slatinný Creek. The deposit was mined with few interruptions until the middle of 19th century.
The main ore zone has a northwest direction and falls steeply to the southwest. It is up to over 20 m wide and consists of a series of greisen little veins about a few decimetres thick. Parallel to it is running another southeast greisen zone, which was developed as a open pit mine (Tagaushieb) with the length of about 320 m. Transversely to them are running other ore-bearing structures - approximately 15 m wide greisen vein in the south and vein Zelený jelen in the north. The richest mineralization occurred at the intersection of these bands, where shafts Medvědí (Bärenzeche), Jánská (Johannizeche) and Jelení hlava (Hirschkopfzeche) were established.
Deposit was mined by two galleries - the hereditary gallery was 360 m long and empted over Slatinný creek, the higher gallery had its entry about in the middle of the slope. Mined tin ore was crushed in local stamping mills, enriched by floating and taken to tin smelter in Nejdek. Recent workings had only exploratory nature and are dated to thirties and fifties of the 20th century. The remains of the mining activities at the site have been preserved until today. The surface excavation is well preserved and well visible are buried mouths of galleries and exploration shafts.
