The Monte Scer\u00e9 area has a subsoil rich in minerals. It is assumed that various metals were extracted there in past centuries, in particular iron, lead, silver and gold. The first earliest documented\u00a0 gold mining attempt\u00a0 date back to 1785. On the banks of the Lisora river, neatly stacked piles of well-worn bowls can be found,\u00a0 representing the remains of gold mining activity dating from the Roman period (Aurifodine).
Until\u00a0 2015, the entrance to the Costa di Sessa mine was abandoned, and inaccessible,\u00a0 hiding an underground maze with over two kilometres of tunnels dug the miners on five different levels.
Thanks to the richness of its subsoil, Malcantone was listed in the national inventory as ‘one of Switzerland’s largest mining districts.<\/p>

There have been two important phases in the exploitation and cultivation of minerals:<\/p>

– in the 19th century, under the direction of engineer Vinasco Baglioni, mainly using laborious manual techniques, the first tunnels were dug in the area of Mount Scer\u00e9 and the first processing plant was established in the area of Molinazzo di Monteggio, which is still known as the Smelter.<\/p>

– In the 20th century, the “Mines de Costano SA” company (1933) started industrial processing by expanding the various existing tunnels and building the mineral processing plant in the Lolina locality.<\/p>

During the Second World War, work was suspended because the mineral concentrate obtained could no longer be sent to Belgium for final treatment. Despite the resumption of mining at the end of the war, the work had a limited duration and in 1952, operations were suspended.<\/p>

Until 2015, the Costa di Sessa mine was abandoned to neglect and oblivion. Hidden in the bush, the entrance had become inaccessible, although in an underground labyrinth, miners had excavated more than two kilometres of galleries on five levels over the course of a century.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Storia della Miniera La zona del monte Scer\u00e9, come tutto il Malcantone, ha un sottosuolo ricco di minerali. Si suppone che gi\u00e0 nei secoli passati si estraessero vari metalli, in particolare oro, argento, ferro e piombo. I primi tentativi documentati di estrazione di oro risalgono al 1785, ma, agli argini del fiume Lisora, ci sono cumuli ordinati di ciottoli lavati che rappresentano i resti della coltivazione di terrazzi auriferi risalenti all\u2019epoca romana (aurifodine). Grazie alla ricchezza del suo sottosuolo, il Malcantone \u00e8 stato inserito nell\u2019inventario nazionale come il \u201cDistretto Minerario fra i pi\u00f9 grandi della Svizzera\u201d. Ci sono state due importanti fasi di sfruttamento e coltivazione dei minerali: nell’800, sotto la direzione dell’ingegner Vinasco Baglioni, principalmente con tecniche manuali molto faticose, furono scavati i primi cunicoli nella zona del monte Scer\u00e9 e fu insediato il primo impianto di lavorazione nella zona di Molinazzo di Monteggio che ancora oggi viene chiamata Fonderia. \u00a0nel ‘900, con la societ\u00e0 “Mines de Costano SA” (1933) si diede avvio a una lavorazione industriale ampliando i vari cunicoli gi\u00e0 esistenti e costruendo gli impianti per il trattamento dei minerali nella localit\u00e0 Lolina. Durante la seconda guerra mondiale i lavori furono sospesi perch\u00e9 il concentrato minerale che si otteneva non poteva pi\u00f9 venir inviato in Belgio per il trattamento finale. Nonostante la ripresa delle coltivazioni alla fine della guerra, i lavori ebbero una durata limitata e nel 1952 le attivit\u00e0 furono sospese. \u200b Fino al 2015 la miniera della Costa di Sessa era abbandonata all\u2019incuria e all\u2019oblio. Nascosta nella boscaglia, l\u2019entrata era diventata inaccessibile, sebbene in un labirinto sotterraneo i minatori avessero scavato, nel corso di un secolo, di pi\u00f9 di due chilometri di gallerie disposte su cinque livelli.
