Element 29 Announces Results from Elida Phase 2 Drill Program including 404.5 metres of 0.60% CuEq1
Vancouver, Canada, March 6, 2023 – Element 29 Resources Inc. (“Element 29” or the “Company”) (TSX-V: ECU | OTCQB: EMTRF | BVL: ECU) announces results from the 2,043-metre (“m”) Phase 2 drill program at its 100% owned Elida Copper Project (“Elida” or “the Project”) located in central Peru (Figure 1).
Elida Drilling Highlights
- Drill hole ELID032 intersected 404.5 m of 0.45% copper (“Cu”), 0.032% molybdenum (“Mo”), and 3.6 g/t silver (“Ag”) for 0.60% copper equivalent1 (“CuEq”, see footnote 1 in Table 1), including 123.0 m of 0.52% Cu, 0.036% Mo and 4.0 g/t Ag for 0.68% CuEq1 starting from the bedrock surface at 45.5 m depth (Figure 2).
- Drill hole ELID031 returned a longer than expected intersection of 366.9 m of 0.27% Cu, 0.027% Mo, and 2.2 g/t Ag for 0.38% CuEq1 (Figure 3), including a 119.1 m interval of 0.38% Cu, 0.025% Mo, and 2.5 g/t Ag for 0.49% CuEq1.
Steve Stakiw, President and CEO, comments, “The Phase 2 drill results from Elida have further boosted our understanding and confidence in the Zone 1 porphyry copper deposit that hosts our initial mineral resource estimate. The program also further confirmed the consistency and continuity of copper mineralization within the Zone 1 resource shell, specifically with hole ELID032 delivering a long, continually mineralized interval of copper averaging above our resource grade as well as ending in mineralization grading 0.75% Cu, 0.032% Mo, 7.2 g/t Ag (0.93% CuEq1).”
The Elida Phase 2 drilling program was designed to evaluate the continuity of Zone 1 mineralization along strike and between widely spaced drill holes completed in Phase 1, and to provide better resolution on the position of the porphyry complex occupying the centre of Zone 1. A secondary objective was to complete initial drill testing of Zone 2 (Figure 1).

- Copper equivalent grades (CuEq) are for comparative purposes only. Calculations are uncut and recovery is assumed to be 100% as metallurgical data is insufficient to allow for estimation of metal recoveries. Copper equivalence (CuEq %) is calculated as: CuEq (%) = Cu (%) + [3.6027 × Mo (%)] + [0.0084 × Ag (g/t)], utilizing metal prices of Cu - US$3.75/lb, Mo - US$13.51/lb and Ag - US$21.63/oz. Metal prices are based on long-term consensus average prices (Bloomberg, S&P Capital IQ, broker research, Canaccord Genuity Corp., March 1, 2023).
- Intervals are downhole drilled core lengths. Drilling data to date is insufficient to determine true width of mineralization. Assay values are uncut.
ELID032 was drilled to examine the west and depth continuity of an internal higher-grade zone intersected by drill holes ELID014, ELID020, and ELID024. Results from this hole show higher grade mineralization persists west and north of the higher-grade mineralization intersected by ELID020. The style of mineralization was similar to surrounding holes with chalcopyrite as the copper-bearing sulphide species (Images 1 and 2). Importantly, only minor intervals of late-mineral porphyry dikes were encountered, meaning there is minimal dilution from lower-grade porphyry units in the northern segment of Zone 1. The drill hole, which was terminated for operational reasons, ended in mineralization at a depth of 450.0 m in mineralization grading 0.75% Cu, 0.032% Mo, 7.2 g/t Ag (0.93% CuEq1). See Figure 2.
ELID031 was positioned east of the higher-grade zones intersected by holes ELID012, ELID019, and ELID025 and on the same section as ELID021. The objective was to obtain an intersection above the mineralization in ELID021 and determine the position of the porphyry complex central to Zone 1. ELID021, drilled in Phase 1, was collared near the northern boundary of Zone 1 and extended south toward the porphyry complex, but was unable to intersect the contact due to drilling equipment limitations. ELID031 was intended to intersect the part of Zone 1 between the end of ELID021 and the porphyry. The hole successfully intersected lower grade mineralization characteristic of the porphyry complex and was terminated in mineralized porphyry phases. The porphyry complex was approximately 100 m further south than was predicted from previous sparse drilling information. See Figure 3.
ELID030 was located on the west side of Zone 1 to determine if the higher-grade mineralization in ELID020 continued to the west. The drill hole penetrated thick, unconsolidated colluvial cover and intersected a short interval of weakly mineralized sedimentary host rock before entering the lower-grade porphyry complex at the centre of Zone 1. The hole demonstrated that the porphyry complex is not a simple elliptical shape as interpreted previously. Geologic evidence from the drilling shows that the porphyry complex was emplaced into well-mineralized sedimentary host rock. Current drilling information suggests the internal higher-grade mineralized zone is displaced to the south by intrusion of the porphyry complex, which is supported by hole ELID020 on the north side of the porphyry complex and hole ELID023 on the south side of the porphyry complex. Further drilling will be required in this area to constrain the position of the porphyry complex and the internal higher-grade zone.
Zone 2 was tested with three (3) drill holes (ELID027, ELID028, and ELID029) positioned near strongly leached exposures of intensely altered and veined porphyry and sedimentary wall rock. Note, the first hole (ELID026) was lost at a depth of 117.7 m and the second attempt was successful at reaching the target depth. All drill holes intersected variably altered sedimentary and volcanic host rocks. Potassic (hydrothermal k-feldspar and biotite) alteration in both porphyry and wall rock was overprinted by phyllic (quartz-sericite-pyrite) alteration. However, only traces of chalcopyrite were present, and the holes returned no significant copper values. Preliminary interpretation of results suggests the holes are located along the poorly mineralized upper boundary of the potassic zone. The initial drilling does not discount the existence of mineralization at depth. However, more work is necessary to develop a deeper drill target. Given that drilling shows Zone 1 copper mineralization ends abruptly with potassic alteration extending for 50-70 m past the mineralized boundary, it is permissive for a mineralized zone to exist at a reasonable depth.
Results from the Phase 2 drilling program improved our understanding of the continuity of mineralization within Zone 1 and increased confidence in the existence of a near-surface, higher-grade zone. Furthermore, results from Phases 1 and 2 show the northern segment of Zone 1 has a horizonal width of at least 250 m, which contributes to a low potential strip ratio. Drill holes from Zone 2 intersected alteration and veining consistent with outcrops in the area but did not intersect significant copper mineralization. This does not discount the possibility of the existence of mineralization at depth, but on-going interpretation of available exploration data needs to be completed to develop drill targets.
The Company plans to use information from the Phase 1 and 2 programs coupled with more detailed surface mapping to design follow-up drilling programs to explore the internal structure of Zone 1 and develop drill targets on the other four zones. Drilling has provided samples of mineralization that can be used for preliminary metallurgical test work. A program involving preliminary metallurgical testing is planned.
