Base and precious metals exploration company Lykos Metals Limited (ASX: LYK) has sighted gold-bearing “diatreme” breccia in first trench at Zekil-Erak Prospect at the company’s 100%-owned Sinjakovo and Cajnice projects in Bosnia-Herzegovina.

Zekil-Erak Gold Prospect
In July 2022, the company initiated a three-trench programme to follow up on 4km2 gold-in-soil anomaly discovered at the Zekil and Erak localities.
During excavation of exploration trenches at the Zekil locality, the geology field team identified a volcanic “diatreme” gold-bearing breccia complex. These breccias were promptly followed-up with sampling in the trench and over nearby outcrops.
A total of 15 samples from diatreme breccias have been collected to date, including new and recent sampling campaigns. These samples returned results up to 5.78g/t gold (1.35g/t gold on average for 15 samples).
The diatreme breccia complex observed in the outcrop appears as a system of several breccia dykes over 70m width. The orientation of these dykes varies from steep north-south in the upper part of the ridge to a moderately dipping northeast-trending direction on the hill slopes.
Trenching at Zekil is progressing well. The first trench, SICH001 has been fully excavated for 520m length and sampled to 300m; all continuous channel sampling results are pending.
The second trench SICH002 has been excavated to 140m out of 180m planned and has not been sampled yet. Excavation of the third trench at Zekil was abandoned, as controls on gold mineralisation at Zekil are now well understood.
Preparations for drill-testing at Zekil will commence in early September. Trenching will commence mid-August at the Erak locality, to the south of the Prospect.
RDK Copper-Cobalt Prospect
Drilling at RDK Prospect is progressing well, with two diamond drilling rigs on site. Two additional drillholes have been completed: SIDD003 and SIDD004 since the last announcement (27 July 2022). Results for the first two drillholes (SIDD001 and SIDD002) are pending, with the assay laboratory currently experiencing slower than usual turn-around times.
Drillhole SIDD003 intersected three broad but weakly sulphidic intervals (veinlets at 52.1- 62.7m, hydrothermal breccia at 63.8-74.1m and veinlets at 134.2-147m interval) with 1-5% pyrite and subordinate chalcopyrite.
Drillhole SIDD004 intersected four strongly sulphidic intervals (hydrothermal breccia at 141- 142.7m, veinlets at 151-152.4, diorite at 216.4-219.3m and veinlets at 224.8-230.7m interval) all with dominant pyrite (5-20%) over chalcopyrite (1-5%).
Upon completion of drillhole SIDD005, one rig will move to the Debela Kosa locality in the northeast of the prospect area to test a strong electro-magnetic conductive anomaly (coinciding with the expected target horizon), while the second drilling rig will move from south of the historic mine to the western side.
