The one we see here corresponds to the artificial type of mountain. As you can see, they are deep holes, so it is important to observe them with caution and not get too close, as there is a risk of falling.

The old mines of Meazuri exploited iron carbonate, which was very abundant in the area. The mineral was very abundant, but its metallic grade was very low, so it was later treated in calcination furnaces to transform it into iron oxide. This procedure considerably enriched the ore, eliminating impurities and increasing its metallic grade between 10 and 20%. Today the route of the old mining train and the tunnels that were excavated to avoid the slopes of the mountain are still preserved.
