Samco Gold Makes Surface Gold Discoveries at Its Corina Project; Adds Coincident Lag Anomalies to IP Targets

TORONTO, ONTARIO--(Marketwired - Sep 4, 2013) - Samco Gold Limited (TSX VENTURE:SGA) ("Samco Gold" or the "Company") is pleased to announce encouraging results of further surface exploration work including a lag survey and further rock chip sampling at its Corina Project in Santa Cruz province, Argentina.

HIGHLIGHTS

  • Lag survey carried out at 25m intervals over the core Cerro de la Mina area previously the subject of geophysical survey.

  • A cluster of gold samples assaying up to 10.2 g/t Au, 170 g/t Ag was identified at Cerro de la Mina, coincident with a strong IP anomaly.

  • A further gold anomaly of 4.9 g/t Au, 53 g/t Ag was recorded 1.3km south of the Cerro de la Mina-Cerro Cubilete target coincident with a further NNW trending IP anomaly that appears to continue south towards the adjacent Cerro Moro project.

  • The Au:Ag ratio is materially higher in the recent samples than that previously identified in samples found at Cerro Cubilete, offering the potential for a different style of mineralization to that already known.

  • Known mineralization at Corina comprises base metal sulfides ± Ag. Samco believes that the correlation between the IP targets and Au-Ag grades may imply that Au-Ag veins similar to those which occur in the adjoining Cerro Moro property are also present. The association between the Au-Ag lag anomalies and a prominent chargeability feature is regarded as encouraging.

  • Strong clusters of anomalous Pb-Zn values in association with Ba, Mn, Mo and As extend south of Cerro de la Mina to the eastern limit of the sample grid (over 1.5km in potential strike). The mineralization appears to be strongly influenced by a NNW-trending structure expressed as a linear I.P. anomaly.

PROGRAM OVERVIEW

Lag geochemistry

The lag survey comprised 23 east-west lines 100 m apart, sampled every 25m. It covers essentially the same area as the geophysical survey carried out over the Cerro de la Mina prospect and its extension to the south, announced on June 17, 2013. Two reference lag samples were also taken over known Ag mineralization at Cerro Cubilete. They assayed 124 and 100 ppm Ag, thus supporting the effectiveness of the method.

Lag geochemistry aims to detect metal anomalies by separating heavier or coarser surface material such as pisolites or quartz fragments from finer-grained exotic components such as volcanic ash from recent eruptions, wind-blown material etc. It is considered a particularly effective method in Patagonia where both recent ash and wind-blown dust are commonly present. In the present survey, the material sampled was sieved to provide a fraction in the plus 3 mm to minus 19 mm size range. Samples were assayed by Alex Stewart Argentina S.A. for Au and Ag by fire assay with an AAS finish, with lower detection limits of 0.01 and 2 ppm respectively. Ag was also analyzed by ICP (Inductively coupled plasma), with lower and upper detection limits of 0.5 and 200 ppm. Ag values reported here are the ICP determinations up to 200 ppm, and the fire assays for samples above 200 ppm. 38 other elements including As, Ba, Cu, Pb and Zn were also determined by the ICP method.
