Base and precious metals exploration company Lykos Metals (ASX: LYK) has provided an update on exploration activities at the Company’s 100%-owned Sinjakovo project in Bosnia-Herzegovina.
Drilling intercepts interpreted historical copper mine horizon at RDK
- The first ever modern exploration drillhole (SIDD001) at Sinjakovo has intercepted the historical copper mine lithological sequence at a depth of only 22.5m down hole
- An 11.5m thick, extensively oxidised mineralised horizon was intercepted in a carbonate rock unit which hosts the nearby high grade historical copper mine
- The drillhole ended in a previously undiscovered sulphide bearing rock unit at a depth of 247.5m down-hole
- Follow-up drilling will immediately target the interpreted down-dip extent of the oxidised zone
At the previously discovered Zekil-Erak prospect
- Latest surface rock chips returned up to 6.94 g/t gold, 183 g/t silver, 4.11% copper and 1.33% antimony
- 2km long trenching program targeting a gold-in-soil anomaly commences
- Final soil infill results returned up to 1.66 g/t gold in soil
Three exciting new outcropping mineralised prospects identified, with early indications of potential “Vares-style” barite and silver mineralisation:
- Kovacevac prospect – rock chips assaying up to 12.15 % zinc, 3.93 % lead and 105 g/t silver
- Prisoje prospect – outcropping rocks with visible polymetallic mineralisation in barite veins observed and sampled, results pending
- Krajevi prospect – soil sampling at newly granted tenement Jezero return encouraging results
At the RDK copper cobalt prospect, the first ever modern exploration drillhole, SIDD001, is complete. SIDD001 intersected the interpreted lithological sequence which hosts the nearby high grade historical copper mine at a downhole depth of 22.5m. This was shallower than expected and in an oxide zone which suggests a ~100m reverse fault between the drilling area and historic mine area. The hole also intersected a sulphidic volcano-sedimentary complex at depth.
The trenching program at the Zekil-Erak prospect targeting a gold-in-soil anomaly has commenced. About 2km of total trenching is planned at the Zekil area and is expected to commence in August. Exceptional recent surface results support an ongoing focus on this prospect and, subject to trenching results, drilling is planned to commence toward the end of the calendar year.
The Kovacevac, Prisoje and Krajevi prospects have been identified since the last exploration update (reported 13 April 2022). Kovacevac and Prisoje were identified following rock chip sampling results taken from areas with outcropping mineralisation. Mapping and drilling are planned to commence toward the end of the calendar year. The Krajevi prospect, returning anomalous lead, zinc and antimony was identified for infill sampling following result from our initial soil sampling program at the Jezero tenement.
All 612 soil samples from the initial program over newly granted Jezero tenement have been collected. About 73% of the samples have been received. The processed geophysical airborne EM and MAG results from the project-wide survey are expected in mid-June, and interpretation of geophysical results is expected by early-July.
Lykos Metals Managing Director Mladen Stevanovic said:
“Our systematic exploration programs across the entire Sinjakovo project area is progressing exceptionally well. At every location we are uncovering evidence of extensive mineralisation events, with surface samples already returning high grade copper, gold, silver, cobalt, zinc, lead and antimony.
“The newly-discovered mineralised zones are adding to our already significant exploration prospect pipeline and our geologists are very excited to continue their work in unravelling the geological story of the area.
“At the RDK prospect, we have successfully completed SIDD001 – the first ever modern exploration drillhole at Sinjakovo. All the indications are that the drillhole has intercepted the historic high-grade copper mine lithological horizon, albeit at a much shallower depth than was expected. An offset fault has long been suspected and SIDD001 suggests that the mineralised horizon could be shallower than anticipated and possibly even subject to repetitions at depth.
“Trenching at the Zekil-Erak prospect is targeting a gold-in-soil anomaly to follow up the outstanding polymetallic mineralisation identified in the soil and rock chip sampling programs. We look forward to a potential drilling program at Zekil-Erak, subject to results. Our initial 2,594-sample, project-wide soil sampling program is now complete, and we look forward to reporting the results from this and the geophysical survey in due course.
“As we continue to receive results, more exciting exploration prospects are emerging. We are delighted by the discovery of the Kovacevac, Prisoje and Krajevi prospects.”
