A recent induced-polarisation (IP) geophysical survey run by Strickland Metals at its emerging Rogozna gold project in Serbia has highlighted what the company says are two targets exhibiting strong chargeability anomalism.
Management says the survey identified the Jezerska Reka and Obradov Potok targets as having bigger anomalous zones, with stronger responses than the anomalies associated with its Shanac and Copper Canyon deposits that comprise a 5.4 million-ounce gold-equivalent resource.
Strickland Metals has used geophysics to nail a pair of prospects that were as elusive as two Serbian wolves and will now target them for porphyry-style gold at its project in the Central European nation.
It believes the two new prospects present significant new near-term opportunities to grow the resource, as both sit directly along strike to the north-west from the current deposits that form the current estimate.
At the Jezerska Reka prospect, a circular IP chargeability anomaly has been defined to measure about 600m by 900m, with a depth extent limit of 400m. It begins near-to-surface and coincides with multi-element geochemical anomalies found in soils and outcropping advanced argillic alteration, which forms clay-type minerals in the exposed rock.
‘The new IP survey data has increased our confidence that the Jezerska Reka and Obradov Potok target areas have the potential to host significant bodies of mineralisation, opening up another exciting new avenue for discovery and growth at Rogozna. The IP anomalism at Jezerska Reka and Obradov Potok is more laterally extensive and of stronger tenor than similar anomalies at Shanac, Copper Canyon and Gradina.’

There were six anomalies identified at Obradov Potok, with the biggest being 1200m in length and 400m wide. It begins at 60m, with the strongest section of the anomaly extending to 120m. The five remaining anomalies are up to 300m long, 150m wide and extend to depths down to 200m and coincide with anomalous soil samples from previous exploration.
The IP surveys were designed to follow up on widespread gold, copper, lead, zinc, molybdenum and bismuth anomalies uncovered in soils from previous programs and which are associated with extensive hydrothermal alteration at surface.
Strickland Metals managing director Paul L’Herpiniere said: “The new IP survey data has increased our confidence that the Jezerska Reka and Obradov Potok target areas have the potential to host significant bodies of mineralisation, opening up another exciting new avenue for discovery and growth at Rogozna. The IP anomalism at Jezerska Reka and Obradov Potok is more laterally extensive and of stronger tenor than similar anomalies at Shanac, Copper Canyon and Gradina.”
The company says there are four rigs working at Rogozna across the Shanac-Medenovac-Gradina deposits, with plans to move one of the rigs to Jezerska Reka in the coming weeks. It notes that historical drilling at Jezerska has identified porphyry-related alteration and veining, confirming the prospect as a high-priority target for porphyry-hosted copper-gold mineralisation.
