Rupice – High Grade Deposit

  • Near-surface sedimentary-style base metal deposit with very high grades of Zn, Pb, Ag, Au, BaSO4 and Cu.
  • Deposit lies approx. 17km NW of the Veovaca pit and historic processing facility.
  • Exploration adits were used to mine 15,000t of high grade Zn-Pb material that was processed at Veovaca.
  • 49 historic drill holes for 5,696m but only 35% of the holes were occasionally sampled for Au and Ag – Adriatic 2017 drilling shows high correlation between Ag and Au & base metals.
  • Historic small scale mining of the outcrop producing approx. 20,000t containing 88.9% BaSO4– sent to USA.

64m @ 8.5% Zn, 5.1% Pb, 374g/t Ag, 2.3g/t Au, 1% Cu & 43% BaSO41 makes Rupice among the highest grade polymetallic deposits globally

 

 

Exploration

The Rupice prospect is located 15 km to the northwest of Veovaca on the western slope of Kiprovac Ridge. Other known prospects include Jurasevac-Brestic and prospects in the Borovica corridor (Kraljeva Jama, Siroki Radakovac, Ceo Sutjeska and Zakruzje).

Exploration activities in the Rupice area commenced in 1952 and continued intermitently until 1990, initially focusing on barite mineralisation and later on the polymetallic mineralisation.

Exploration activities including geophysics (IP – chargeability), costeans, exploraion adits, and drilling. These indicated the presence of polymetallic mineralisation at Rupice and Jurasevac-Brestic. Chargeability anomalies extend to the south-east between Rupice and Jurasevac-Brestic but these trends have not been drill-tested. Other anomalies in the area (at Gornja Borovica and Donja Borovica localities) have not been followed up by drilling either, though these are outside the Adriatic granted Concession.

During this period Energoinvest completed 59 holes for 7,000 m targeting Rupica, Borovica and Jurasevac-Brestic.

Rupice Long Section

  • Pb+Zn mineralization extends from surface and dips to the NNE.
  • Hole BR10-81 also intercepted Au over 30m @ 1.78 g/t and Ag @ 195 g/t. Hole BR14a-81 intercepted 21m @ 2g/t Au from 2m.
  • Hole BR24-82 also intercepted Au over 8m @ 1.43 g/t and Ag @ 319 g/t. Less thatn1/3 of holes in Rupice were assayed for Ag/Au.

  • High grade orebody (bright orange) subcrops in several areas and is plunging/open to the N/NE.
  • Mineralisation extensions (shaded orange) outside the high grade zone with a NE dipping orebody.
  • IP chargeability also indicates possible extension to the west and southeast which will be drill tested in 2018.
  • Clear relationship between base metal and precious metal grades suggest potential to add Au and Ag to a future JORC Resource.

Rupice Area – IP Chargeability Anomalies

  • Numerous IP anomalies indicate these projects form part of a broader polymetallic district, with immediate targets in the Rupice and Borovica Corridor.
  • These IP anomalies correlate with historical work -trenching, exploration adits and limited drilling.
  • Adriatic has commenced geophysics and geochemistry work to further define exploration drill targets.
