Adriatic Metals has identified a number of new multi-metal exploration drill targets after modelling historical gravity data over its Bosnian license that includes its Rupice and Jurasevac-Brestic prospects. Some of the geophysical anomalies are adjacent to known discoveries and are ready for immediate drilling with a total of 29 drill pads approved for action already to further define the extraordinary multi-metal deposits within its project area.
Adriatic completed a detailed ground gravity geophysical survey over Rupice and Jurasevac-Brestic in early 2018, around the time of its ASX-listing. This data has now been re-modelled utilizing the latest detailed Lidar topographic data acquired by the Company in late 2019 to define a number of significant anomalies.
Management said that gravity data is a powerful tool when massive sulphide and barite mineralisation is present. The density contrast between the barren host rock and mineralisation, when mineralisation is present, shows a gravity high. The new gravity data at Rupice confirms the massive sulphide deposit and barite mineralisation seen from the resource drilling.
Adriatic’s technical team said that additional high-priority drill targets are apparent at the Jurasevac-Brestic prospect, to the east of the historic Jurasevac adit, with drilling to re-commence there shortly.
A number of additional gravity anomalies have also been identified within the license which warrant future drill testing. Adriatic’s own drilling at Jurasevac-Brestic has previously encountered patchy, vein-style mineralisation, in line with other historical drill results, but no massive sulphide mineralization has been detected.
The company’s technical team now believe the new gravity data indicates that drilling may have been targeting too far west, with the peak of the gravity anomaly being on the eastern side of the prospect.
The rotary divining will continue over coming months as operations on site are largely unaffected by the current coronavirus crisis.
No doubt Adriatic will be looking to replicate some of the prior spectacular results at the project including 64m @ 4.6g/t gold, 537g/t silver, 0.9% Copper, 7.7% lead, 10.8% zinc and 46% barite.
Adriatic Metals Managing Director and CEO, Paul Cronin said: “from the reprocessing of the gravity data, we can see that gravity correlates extremely well with the known high-grade mineralisation that we see at Rupice. This style of mineralisation usually occurs in clusters, and the fact we also see a large, intense anomaly at Jurasevac-Brestic is extremely encouraging. We intend to get a drill rig to test this as soon as one becomes available”. He added “there are a number of additional anomalies seen between Rupice and Jurasevac-Brestic, that will also need testing."
"We have five rigs operating and hope to have a 6th rig operating once the Bosnian border re-opens to our foreign based drill crews. The Bosnian government response to the COVID-19 issue has required us to conduct some contingency planning for potential logistical issues, but to date is not having a major impact on the drill program, the pre-feasibility work or permitting, which are our 3 predominant work streams for the first half of 2020. We will continue to monitor the situation for potential impacts and implement contingency plans if needed.”
