Helicopter-borne time-domain electromagnetic (“TDEM”) and ground-based gravimetric surveys have begun but are progressing slowly due to poor weather conditions in the permit area over the last two weeks.
Key takeaways from the exploration work carried out at the Lomero-Poyatos Project to-date include:
- These additional validation and infill drill holes continue to confirm the grades and widths of intersections in selected drill holes from previous drilling campaigns, increasing the confidence in the geological understanding and data validation that will be carried out for the Mineral Resource estimate;
- Current infill drilling continues to intersect medium to high-grade gold and polymetallic mineralization, mainly associated to thick intersections, over 350 meters strike length below Level 5 of the historical mine in the central and eastern portions of the deposit. Infill drilling also continues to show increasing zinc and gold grades in progressively narrow massive to semi-massive intersections at depth at the western end of the permit;
- Field mapping suggests a potential eastern extension of the shear-zone that hosts the Lomero-Poyatos deposit, which bends to the NE and appears to be limited by the presence of an inferred NE-trending fault at the easternmost end of the mine;
- Sulphide mineralization includes polymetallic (sphalerite and galena) mineralization. It is not typical to have sphalerite and galena occurring together with chalcopyrite in a VMS system. As polymetallic mineralization was encountered in a deeper part of the Lomero-Poyatos shear zone, and the higher areas of the same shear zone do not contain polymetallic mineralization, this may indicate further polymetallic mineralization occurs at depth that is being sheared into the chalcopyrite and pyrite mineralization.
Serafino Iacono, Executive Chairman and CEO of Denarius, commented, “These additional drilling results continue to confirm the widths and grades of gold and polymetallic mineralization of previous drilling campaigns on the Lomero -Poyatos Project and demonstrate the continuity of wide, high-grade gold and polymetallic mineralization below Level 5 of the historical mine over 350 m strike length. We are also confident that our geophysical program will expand the prospectivity for new deposits potentially associated to the northern and southern shear-zones relative to the known shear-hosted Lomero-Poyatos deposit. The ongoing drilling program has verified the reliability of the historical drill results and will allow proper 3D modelling of the deposit in order to prepare an updated NI 43-101 compliant mineral resource estimate and scoping study by the third quarter of this year".
To date, 100% of the Validation phase and 70% of the Infill phase have been completed.
The Company has established COVID-19 safety protocols for ensuring a secure work environment for its employees and contractors.
Key Highlights
- New results from three validation holes in the ongoing drilling program largely validate the thickness and grades of selected drill holes from previous drilling campaigns as shown by the table below:
- Drill hole LM22025, along with drill holes LM21007, LM21009, LM21010 and LM21014 (previously reported), was successful in confirming high-grade gold and polymetallic mineralization over 250 meters of strike length below Level 5 of the historical mine in the central and eastern portions of the deposit, demonstrating that mineralization is continuous and open at depth. The mineralization is characterized by a massive polymetallic sulfide zone with drill intersection widths of between 6.45 m and 17.70 m with average grades of 0.38 to 2.51% copper, 0.18 to 3.28% zinc, 0.16 to 0.65% lead, 15.74 to 62.49 g/t silver and 1.84 to 6.07 g/t gold. This high-grade portion of the deposit is extended west by drill hole LM22023 to a lower grade for an additional 100 meters.
The grades are higher when the massive sulfide zone is predominant. The widths are drill intersections across the mineralized zones and the true width is estimated to be approximately 80-90% of the drill intersections.
- Drill hole LM22024 continues to show increasing zinc and gold grades in progressively narrower massive to semi-massive intersections at depth at the western end of the permit. Narrowing of the intersections is offset by high-grade zinc and gold mineralization as shown by CuEq grades and In-situ Rock Values, see table below.
- The Lomero-Poyatos shear zone appears to trend east-west across the middle of the property. Historical level plans and mine workings suggest that the deposit bends northeast to the east of Lomero, however, no field evidence is currently available to evaluate this change in orientation. Sheared dacite observed in the Rivera de la Pelada may suggest the shear zone continues to the east, which will be tested by the ongoing high-resolution helicopter-borne time domain electromagnetic (“TDEM”) and magnetic survey (Xcite™).
- Copper sulphide mineralization in drill hole LM22025 includes polymetallic (sphalerite and galena) mineralization. It is not typical to have sphalerite and galena occurring together with chalcopyrite in a VMS system. As drill hole LM22025 intersected in a deeper part of the Lomero-Poyatos shear zone, and the higher intersections do not contain polymetallic mineralization, this may indicate further polymetallic mineralization continues at depth, which will be tested by step-out drilling.

Qualified Persons Review
Dr. Stewart D. Redwood, PhD, FIMMM, FGS, Senior Consulting Geologist to the Company, is a qualified person as defined by National Instrument 43-101 – Standards of Disclosure or Mineral Projects and prepared or reviewed the preparation of the scientific and technical information in this press release. Verification included a review of the quality assurance and quality control samples, and review of the applicable assay databases and assay certificates.
Quality Assurance and Quality Control
The Lomero-Poyatos samples were prepared and assayed by AGQ Labs (ISO/IEC 17025) at their laboratory in Burguillos, Seville, Spain. Gold was assayed by 30 g fire assay with ICP-OES finish, while silver and base metals were analyzed in a multi-element package by aqua regia digestion and ICP-OES finish. Blank, standard and duplicate samples were routinely inserted and monitored for quality assurance and quality control.
