Key takeaways from the exploration work carried out at the Lomero-Poyatos Project to date include:
- Validation and in-fill drill holes have generally confirmed the grades and widths of intersections from previous drilling campaigns, increasing the confidence in the geological understanding of the deposit and allowing proper 3D modelling in preparation for a Mineral Resource estimate update by the end of the third quarter of 2022;
- Drill hole LM22053 was the highlight of the current set of drill holes intersecting 2.65 meters grading 1.69% copper, 0.8% lead, 0.5% zinc, 115.44 g/t silver and 9.56 g/t gold from 268.35 meters;
- Preliminary results from the integrated interpretation of the recently completed geophysical surveys (NRG Europe's high-resolution Xcite™ TEM/MAG and gravimetry acquired by IGT of Madrid, combined with legacy gravimetric data, have identified significant new targets and demonstrate that conductors associated with the known deposit persist to depths well below the existing drilling;
- The geophysical results are robust enough to allow the planning of an exploration drill campaign aimed to test the combined TEM and gravity anomalies that occur along strike and down-dip of the main shear-zone hosting the Lomero-Poyatos deposit. A parallel shear-zone detected below the Devonian hanging-wall unit and located approximately 1 km north of the Lomero-Poyatos deposit, the Northern Shear Zone, will also be prioritized for drill testing;
- Drill core coarse reject samples to run the first phase of the upcoming metallurgical testing program have already been selected and ready to be shipped to a lab in UK.
Serafino Iacono, Executive Chairman and CEO of Denarius, commented, "We are excited by the progress to date and particularly to be moving the exploration program into the expansion drilling phase as the preliminary results from the integrated interpretation of the recently completed geophysical surveys have expanded the prospectivity for new deposits potentially associated to the down-dip and eastern extension of the shear-zone hosting the Lomero-Poyatos deposit. We are also very encouraged to see other anomalies parallel to the main Lomero-Poyatos shear zone, increasing even further the prospectivity of Denarius' land package in this prolific metallic belt. The ongoing drilling program has verified the reliability of the historical drill results and will allow proper 3D modelling of the deposit to prepare an updated NI 43-101 compliant Mineral Resource estimate and scoping study by the end of the third quarter of this year. We are confident that our exploration campaign at the Lomero-Poyatos Project will continue to be a key value driver for Denarius as we move forward."
Key Highlights
- Preliminary results from the integrated interpretation of the recently completed geophysical surveys (NRG Europe's high-resolution Xcite™ TEM/MAG and gravimetry acquired by IGT of Madrid combined with legacy gravimetric data) provide an accurate reconstruction of the main mineralized horizon that matches the E-W trending shear-zone that hosts the Lomero-Poyatos deposit, which is well marked by coincident conductivity and density (gravimetry) highs. The results show that the eastern extension of this conductor continues over a strike length of 1.5 km, still within the exploration permit, and is open down-dip (see attachment 1).
- Sections L2150E and L2200E, shown in attachments 2 and 3, are good examples of the systematic coincidence of the density and conductivity highs with each other and with the massive sulfide body as shown by the location of the drill hole traces. These sections are typical of the deposit. The main conductor that is associated with the known massive sulfides continues to depths well below the current drilling and is open down-dip. This provides drill targets at depth.
- The geophysical results have also corroborated a recent field mapping discovery coincident with an additional E-W trending shear-zone, called the Northern Shear Zone, that occurs below the Devonian hanging-wall unit located approximately 1 km north of the shear-zone hosting the Lomero-Poyatos deposit.
- The eastern extension of the Southern Shear Zone is clearly delineated by a gravity anomaly and appears to be offset or truncated by a NW-SE trending fault (Attachment 1). This confirms the results of field mapping. The central and western parts of this shear zone were not fully covered by the gravimetric survey, and the conductivity is subject to strong interference from power lines (Attachments 2 and 3), but the target is well defined by field mapping.
- New results from two validation holes in the ongoing drilling program largely validate or improve the thickness and grades of selected drill holes from previous drilling campaigns as shown by the table below:
| Surface Drilling |
| Hole | Phase | From (m) | To (m) | Width (m) | Cu % | Pb % | Zn % | Ag g/t | Au g/t | Min. Type |
| LM22029 | Validation | 159.40 | 160.85 | 1.45 | 0.96 | 0.28 | 0.21 | 27.32 | 2.94 | MS |
| L03-33 | CMR | 156.00 | 158.00 | 2.00 | 1.15 | 0.58 | 0.34 | 28.00 | 2.68 | MS |
| LM22031 | Validation | 50.30 | 50.80 | 0.5 | 0.3 | 0.25 | 0.12 | 33.4 | 2.96 | MS |
| L03-36 | CMR | 56.00 | 59.00 | 3.0 | 0.04 | 0.19 | 0.46 | 6.33 | 0.28 | Minor Sulfides |

- In-fill drill holes mostly confirmed widths and grades of intersections in drill holes from previous drilling campaigns with maximum intersection grades of 0.88% copper, 0.53% lead, 1.79% zinc, 37.53 g/t silver and 4.95 g/t gold over 6.60 meters (LM22047), 1.69% copper, 0.84% lead, 0.59% zinc, 115.44 g/t silver and 9.56 g/t gold over 2.66 meters (LM22053), and 0.37% copper, 1.43% lead, 3.16% zinc, 32.59 g/t silver and 1.59 g/t gold over 6.60 meters (LM22063);
- 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;
- In-fill drilling confirms that the massive and semi-massive sulfide lenses are deformed and pinch and swell abruptly over short distances along strike and down-dip;
- Most of the deepest holes indicate that the massive sulfide mineralization appears to be thinning at depth due to ductile deformation, as the sulfide mineralization is strongly deformed and foliated. No significant brittle faults are observed. Interestingly, the stockwork mineralization does not appear to thin. However, the geophysical results suggest that the massive sulfide mineralization may be widening well below the limit of existing drilling.
- The planned metallurgical testing program has the following goals:
- Determine the amenability of mineralized samples to beneficiation using standard polymetallic base metal sulfide flotation methods.
- Determine the gold deportment, modal occurrence and recovery.
- Separate arsenian pyrite from low arsenic pyrite via selective flotation.
- Samples of coarse rejects from drill core have been selected and are ready to be shipped to a lab in the UK.

*IRV: In-situ Rock Value
Notes:
(1) The holes were drilled at -65 to -85 degrees from the horizontal. Grades are for semi-massive to massive sulfide intersections and some stockwork zones. Sample interval grades over CuEq >1% are reported. The width is the sample length and is not necessarily the true width of the intersection. All base and precious metal grades are uncut and are not diluted to a minimum mining width.
(2) The following holes returned intervals grading
(3) Equivalent copper grade (CuEq %) and in situ rock value (IRV) were calculated using prices of US$1,800/oz gold, US$25/oz silver, US$3.55/lb. copper, US$1.00/lb. zinc and US$0.90/lb. lead. No adjustments were made for recovery as the project is at an exploration stage and metallurgical data to allow for estimation of recoveries is not yet available.
(4) MS: massive sulfides; SM: semi-massive sulfides; STK: stockwork; DISS: disseminated.
Please refer to the attached illustrative images showing the Vertical Gravity Gradient Map, geophysical cross-sections L2150E and L2200E, location of drill holes, and four cross sections for drill holes LM22029, LM22047, LM22053 and LM22063 (Attachments 1 to 8).
