Adriatic Metals PLC (ASX: ADT, FSE:3FN) has announced a highly encouraging update from the drilling at its Rupice project in Bosnia and Herzegovina.

The company reported that drill hole BR-43-19 intersected some of the best high-grade mineralisation in the southern extensions of the Rupice mineralisation, which include 16m @ 1.96g/t Au, 350g/t Ag, 5.3% Zn, 3.4% Pb, 0.5% Cu and 43% BaSO4 from 330m.

ADT reported that the two southern most drill holes have now established that extensions of the high-grade mineralisation are continuous over 550m, and remains open along strike in the south towards the Jurasevac-Brestic prospect.

Rupice project

The Rupice Project is an advanced exploration project which exhibits exceptionally high grades of base and precious metals.

The project is situated within ADT’s Vares Project, located in Bosnia and Herzegovina and is located approximately 12km North West of the Veovaca Project.

In 2017, the Company completed an 8 hole, 1,458 metre diamond drilling program at the Rupice Project, to confirm the historical results and the presence of precious metals with the base metals.

Since 2018, Adriatic has completed over 12,000m of exploration drilling, expanding the known area of mineralisation, and defined some of the highest-grade poly-metallic intercepts globally.

In late 2018, Adriatic drilled hole BR-36-18 which returned 72m @ 2.5g/t Au, 211 g/t Ag, 2.5% Cu, 10.7% Pb, Zn 18.3% and 25% BaSO4, making it the highest grade and thickest intercept to date.

Drilling at Rupice project

The company has now reported the drill results from drill hole BR-43-19, which is the deepest drill hole to date in the southern extensions of the Rupice mineralisation.

ADT said that the results may represent another substantial thickening of the Rupice mineralisation as it extends to the south into untested ground.

Other drill holes in this drill section includes BR-27-19, and BR-37-19, which extends the mineralisation some 200m down-dip and outside of the current ore block model (OBM). The mineralisation remains open down dip and to the south.

The company reported that the drill hole BR-39-19, the deepest hole in the norther extensions of the Rupice mineralisation, intersected an upper lens of 58m of low-grade mineralisation (including 2 intervals of internal waste) and a further two lower lenses of 8m and 6m respectively.

The company said that the drilling in the northern extension is over 80m along strike and outside of the current OBM. The mineralisation remains open to the north.

High-grade intercepts from BR-43-19  

The company reported that drill hole BR-43-19 intersected some of the best high-grade mineralisation in the southern extensions of the Rupice mineralisation.

Significant hits include 16m @ 1.96g/t Au, 350g/t Ag, 5.3% Zn, 3.4% Pb, 0.5% Cu and 43% BaSO4 from 330m including an interval of 10m @ 2.83g/t Au, 536g/t Ag, 7.4% Zn, 4.8% Pb, 0.5% Cu and 60% BaSO4.

The company said that BR-43-19 is deepest intercept to date at Rupice approximately 20m east of the interpreted eastern fault and 60m east of the closest intercept in BR-27-19.

Results confirm extensions of the high-grade mineralisation

The company reported that the results from the two southern most drill holes, BR-41-19 and BR-43-19 confirm extensions of the high-grade mineralisation which is now continuous over 550m, and remains open along strike in the south as drill coverage extends towards the Jurasevac-Brestic prospect.

ADT said that the drilling continues at both the Rupice deposit and the Jurasevac-Brestic prospect.

Management comments

Paul Cronin, Adriatic’s Managing Director and CEO, said: “The latest drill results in the southern extensions of the Rupice deposit clearly demonstrate that the high-grade mineralisation continues outside our current Mineral Resource and south towards our Jurasevac-Brestic prospect a further 500m to the southeast.

This is our deepest high-grade intercept to date at Rupice and given its location to the east of the current mineralisation, opens the deposit to reinterpretation of the structural controls that have led to the thickest and highest grade results on the eastern down dip extent”.
