Canadian-listed Eurotin Inc. has published a maiden NI43-101 resource estimate for its Oropesa project. Based on a cut-off grade of 0.3% Sn, indicated and inferred resources amount to 5.79 Mt of ore at an average grade of 0.47% with 27,480 tonnes of contained tin. The resource confirms the positive open-pit potential of the Oropesa tin deposit, located 180km north east of Seville in southern Spain. Oropesa is a hard-rock deposit on which the company has focussed its exploration efforts recently, with up to five drill rigs in operation. It also controls the Santa Maria project, which is a mix of colluvial and potentially alluvial ores.
In a statement the company noted that “the deposit remains open in all directions and has the potential to expand in terms of both grade and tonnage, as evidenced by recent drilling. The resource was undertaken on the assumption that any future mining will be carried out using low-cost, open-pit methods. Consequently, the resource block model depth was restricted to 200 metres below surface.” Peter Miller, president and chief executive officer, commented: “Now that we have our initial resource, we have passed a significant milestone on our way to building a viable tin mining operation at Oropesa.”
