Salave Gold Project, Spain
Astur Gold (TSX-V: AST, FWB: CDC) is developing its 100% owned Salave Gold Project in Asturias (northern Spain) comprising six mineral concessions covering 686 hectares and an investigation permit covering another 2765 hectares. Drilling to date totals 67,508m in 440 holes (245 diamond drill holes) and metallurgical tests indicate gold recoveries over 90% are possible. The Company is currently conducting a Feasibility Study on Salave based upon underground-only mining via open stope mining methods, bulk backfill with development muck and paste fill, and processing via conventional flotation to produce a gold-rich concentrate for shipment to an independent smelter.
View our Salave Project Photo Gallery Salave was once one of the largest gold mines in the Roman Empire. Mining has a rich history in the Asturias region of the Iberian Peninsula, with a legacy of generations of Asturian miners dating back to the Roman period. The Salave deposit is situated at the bottom of an old Roman open pit, actively mined 2000 years ago. The Romans removed millions of tonnes from the shallower oxidized portion of the deposit in the vicinity of "Los Lagos".
The Company is focused on bringing Salave into production as soon as possible as an underground mine with a simple flotation plant to produce a high grade gold concentrate for shipment to an offsite smelter. Astur Gold is currently in discussions with several smelters. No cyanide will be used on site and no autoclave will be required for ore processing.
Astur Gold is advancing Salave towards production and building a partnership with the people of Asturias in developing economic prosperity for the region. The region boasts excellent infrastructure and industrial skilled labour due to a long history of mining that will help support future mine development. Access to power, water, and roads is available on site.
Location & InfrastructureThe Salave gold deposit includes six mineral concessions covering 686 hectares and an investigation permit covering another 2765 hectares. Access to the Salave property is by paved roads from Oviedo, the Capital of Asturias, northwestern Spain. Logistical support, in terms of power and telephone lines, is available at Tapia, which is linked to the Asturias Power grid. Water is available from wells near the property and from the Porcia River east of the property. A high voltage power line and a rail line transect the property, and shipping facilities are available at the port of Ribadeo , approximately 10 km west of Tapia, within the Province of Galicia. The region boasts excellent infrastructure and a long history of coal mining that will help support future mine development.
Salave Concessions & Investigation Permit Area
Geology & ResourcesGold mineralization at Salave is found within of a series of northwest plunging lenses of disseminated and stockwork-type sulphides, chiefly pyrite and arsenopyrite, hosted by a granodiorite intrusive and overlain by sedimentary rocks. The deposit contains gold mineralization along numerous north to northwest trending and gently west dipping irregular lenses. The individual lenses are controlled by a series of contact parallel structures and associated surrounding micro-fractures. A near vertical feeder structure has been postulated to occur in the vicinity of the high grade mineralization and may be related to northeast trending structures.
Gold mineralization has been delineated over an area of approximately 300 X 350 meters. The dimensions of the individual mineralized zones range from 50m to 200m in length, 10m to 50m in width, and 10m to 60m in thickness, with an average thickness on the order of 19m. The thickness is dependent on the number of contact parallel structures and their influence on the fracturing of the surrounding rock.

- Rounding may cause apparent discrepancies
- Mineral resources that are not mineral reserves do not have demonstrated economic viability
- Resource estimate conducted by Mine Development Associates, Inc. effective date of January 22, 2014
The resource cut-off grade of 2.0 g/t Au was chosen to capture mineralization that is potentially amenable to underground mining, sulfide concentration, and gold recovery using off-site processing. Due to the necessity to maintain a surficial crown pillar in a potential underground operation, all material from the present surface to a depth of 40 meters is not included in the Salave resources.
