Slide 30: PMV – Main Attributes
PMV – Main Attributes ▪ Overview ‒ 100% owned by Atalaya Mining ‒ Along the prolific southern domain of the world-class Iberian Pyrite Belt ‒ Large, NI 43-101 compliant mineral resource based on two nearby VMS deposits: Masa Valverde and Majadales ‒ Resource growth potential ‒ Enormous exploration u
Slide 31: PMV – Overview
PMV – Overview ▪ Two main deposits: Masa Valverde (“MV”) and Majadales (“MJ”), both located along the same stratigraphic and structural setting ▪ MV is one of the largest, single, undeveloped VMS systems in the world ‒ It remains open to the west ‒ MJ is smaller but shallower and higher grade ▪ Very

Slide 38: MV – Mineral Resource Estimate
MV – Mineral Resource Estimate ▪ Resource block model based on 3 geological zones: upper and lower massive sulphides and a stockwork in between ▪ Blocks were regrouped in two extra subzones: a Zn- rich sub-zone (Zn > Cu*2.80) and Cu-rich sub-zone (Zn <Cu*2.80). Cu-rich sub-zones account for most of
Slide 39: MJ – Mineral Resource Estimate
MJ – Mineral Resource Estimate ▪ Resource block model based on three major styles of mineralisation, each with geological and statistical differences ‒ Massive sulphide ‒ Semi-massive sulphide ‒ Stockwork ▪ Polymetallic massive sulphides are predominant ▪ Smaller but shallower and higher grade than
