Cordoba Minerals Corp. is pleased to announce that the final drill holes from the recently completed diamond drilling program have shown large widths of copper-gold mineralization in the newly identified southern extension of the Montiel East target of the San Matias project.
Additionally, the interpretation of over 250 stream sediment samples collected over the main north-south structural trends, located from airborne magnetics data, has shown numerous and extensive copper-gold and gold anomalous drainages over the entire 13 kilometres of strike of the project area, with at least three parallel north-south structural trends that host mineralization, located to date.
HIGHLIGHTS
Montiel East Diamond Drilling
- SMDDH012: 200.1 metres @ 0.42% Cu and 0.33 g/t Au or 0.66% CuEq; including 118.39 metres @ 0.71% Cu and 0.56 g/t Au or 1.10% CuEq
Stream Sediment Sampling
Three parallel north-south trending structures defined by airborne magnetics, each of approximately 13 kilometres strike length entirely within the San Matias project, contain multiple trends of anomalous copper- gold and gold drainages of greater than 2 kilometres strike individually, including:
- Costa Azul - Buenos Aires: 3.4 kilometre trend of copper-gold anomalous drainages
- Valdes: 2.5 kilometre trend of copper-gold anomalous drainages
- Pepita: 2 kilometre trend of copper-gold anomalous drainages
- Caño Pepo: 2 kilometre trend of gold-copper anomalous drainages
- Nieves: 2 kilometre trend of gold anomalous drainages
- Betesta: 1 kilometre trend of gold anomalous drainages
Betesta Target
Soil sampling at the Betesta target, the first of the newly defined target areas from the stream sediment sampling program, has identified a robust gold-in-soil anomaly of 800 m x 900 m dimension with grades up to 1.43 g/t Au and remains open in all directions.
Mario Stifano, President and CEO of Cordoba commented: "Drilling at our San Matias project continues to define broad zones of high grade near surface copper-gold mineralization. The commencement of the ground magnetics program will better define the magnetite alteration that is closely associated with the high grade zones for follow-up drilling. The extensive surface sampling and exploration work has clearly identified three large copper and gold trends and with the recent granting of Mining Titles the Company can now drill these additional high priority targets."
MONTIEL EAST
Final drilling results at the Montiel East target have returned large mineralized intervals at the southern extensions of the copper-gold porphyry that shows the mineralization remains open to the south and south- east where much larger volumes of mineralized porphyry have been located, greatly increasing the size of the target due to it dipping to the south and south-east under mafic volcanic country rocks (Figure 1). The porphyry copper-gold mineralized phase is associated with a series of porphyry dyke and sill-like intrusives of varying phases and incorporates both sheeted and stockwork quartz-magnetite-chalcopyrite-bornite veins within strongly potassic altered diorite porphyry. Minor copper-gold mineralization is also hosted within the mafic and intermediate volcanic hostrocks as multi-directional quartz-magnetite-chalcopyrite-bornite veins which are adjacent to porphyry margins. The mineralized zone was partially terminated where the diorite porphyry phase was intruded by a post-mineral quartz-feldspar porphyry phase. However, numerous smaller mineralized intervals until the end of hole indicate that the mineralized diorite phase is continuous to the south and south-east. The high magnetite content associated with the copper-gold mineralization in the diorite porphyry phase is expected to respond well to a magnetic survey based on magnetic susceptibility tests carried out on drill core to date and a detailed ground magnetics program covering the entire Montiel target has commenced to better define the extensions.
