OK....I have worked out it is a "brownfield" project....as Rubiales is an old mine which is part of the Toral License....
I picked this up from old Lundin mining article.
The property covers over 6 km of strike length of the prospective Lower Cambrian Vegadeo Limestone formation which is regionally mineralized along more than 40 km of its extent, and includes hosting the Rubiales zinc-lead-silver deposit, located about 30 km northwest of Toral. Rubiales contained an 18.6 million tonne mineral resource grading 7.3% Zn, 1.3% Pb and 13 g/t Ag and was mined by Cominco from 1976 to 1991. Rubiales produced extraordinarily high-quality zinc concentrate (life-of-mine average of 61% Zn with 95% zinc recovery); the lead concentrate contained 70% Pb and 450-550 gpt Ag with an 85% lead recovery. The concentrates were transported to the Asturianas zinc-lead smelter, located on the Asturias coast about 200 km to the west. The Asturianas smelter was designed to recover the mercury (0.16% Hg in concentrate) contained in the Rubiales zinc concentrate as a saleable product. Sulphide mineralization at Toral closely resembles the coarse-grained sphalerite and galena mineralization at Rubiales but Toral contains significantly more silver. The Toral property is accessed by excellent infrastructure, including a regional highway, high-voltage power line and a railway line which links to the Asturianas zinc-lead smelter via the city of Leon. Mining has traditionally been a significant part of the economy of this region which is strongly supporting the re-entry of new exploration and mining projects.
