The drill gap program:
- confirmed rare-earth components (REE) mineralization acknowledged by geological work, together with geochemical sampling continued at depth.
- acknowledged that the mineralization happens primarily within the first 15m under floor, with an financial horizon of roughly 7m.
- confirmed that REE are extremely absorbed into ionic clays leading to a excessive share of REE exchangeable fraction restoration (see desk 3).
- confirmed enticing recoverable values of the heavy uncommon earths (HREE,) Dysprosium and Terbium (DyTb), in addition to the sunshine uncommon earths, Neodymium and Praseodymium (NdPr).
- confirmed that the mineralization stays open on its lateral extents at completely different topographic ranges.
Ramón Barúa, CEO of Aclara, commented:
“Preliminary exploration outcomes at Veronica North signify step one in direction of turning into a multi-modular HREE Firm. As we progress, our in-house developed exploration mannequin has confirmed extremely efficient find REE-enriched ionic clay deposits. We’re very inspired with these outcomes and plan to proceed with additional drilling campaigns to unlock the complete potential of the asset”.
A location map is proven in Determine 1, the place the complete Veronica district is displayed masking roughly 13,122Ha in excessive precedence drilling areas, comprising of Veronica Norte (5,055Ha), Verónica Centro (2,492Ha) and Veronica Sur (5,575Ha). The drilling marketing campaign executed in 2022 is especially concentrated within the north of Veronica Norte. Drill holes, averaging 25m in depth, intersected mineralization with TREY (complete uncommon earth plus yttrium) financial grades; the interception size and common composite grades (ppm) of those intersections are proven in Desk 1.

Patricio Irribarra, Head of Geology at Aclara, commented:
“The drill holes within the Veronica Norte space had been designed to (i) verify the presence of REE mineralization beneath the great outcomes obtained throughout floor geochemical scan and sampling, (ii) check different targets within the space and eventually, (iii) perceive the geological components that management the mineralization.
Verónica Norte shows completely different traits to the Penco Module, equivalent to being a shallower but probably bigger deposit, with decrease grades however with a considerably increased exchangeable REE fraction with fascinating ranges of each DyTb and NdPr. We’re inspired that Veronica Norte mineralization stays open on its lateral extents at completely different topographic ranges, producing new concentrating on zones and rewarding our exploration efforts. We have now determined to proceed with the drilling and sub-surface sampling within the Veronica Norte space, concentrating on different sectors to maintain evaluating the positioning potential and its extension.
The areas of Veronica district had been closely impacted by the fires throughout February, which has put a short lived restriction to re-initiate drilling works. Through the summer time season, we are going to hold serving to the affected communities on website in addition to collaborating with forestry corporations. We intend to renew greenfield campaigns on the acceptable time as soon as we obtain clearance from superficial land homeowners.”
The Challenge hosts uncommon earth components mineralization absorbed into an ionic clay deposit, which is shaped by the weathering of calc-alkaline with peraluminous sign rocks as protolith, containing REE bearing and accent minerals equivalent to monazite, allanite, and apatite, and as impurities in main minerals. Because of floor weathering, REE containing minerals are decomposed, and ionized REEs are absorbed on the floor of clay minerals equivalent to halloysite and kaolinite.
In accordance with the geological mapping and the knowledge obtained from the Veronica Norte 2022 drill gap marketing campaign, the native geology is proven to be homogeneous, outlined by two lithological Models (Determine 2B). Predominating in areal extent is biotite granitoid (TBT) and, to a lesser extent, within the northern portion of the world, a diorite (DRT). The chemical outcomes of each Models don’t present vital variations in grade values, implying a priori the shortage of lithological management of the mineralization. Regardless that mineralized DRT tends to be richer in TREY, the extent of TBT within the space presents extra curiosity, contemplating it additionally reaches probably financial values of its exchangeable fraction. The regolith profile proven in Determine 2A is characterised not solely by its noticed geological standards (texture, alteration grade, mineral composition), but in addition by its chemical information, which helps restrict their extent, narrowing the horizon internet hosting the mineralization. Topography seems to manage the formation and preservation of the mineralized horizon, being current at completely different topographic altitudes, the place the exchangeable fraction of the mineralization is hosted at shallow depths (between the primary 10-15 m).
Because the mineralization is managed primarily by the weathering/regolith growth as an alternative of the lithology, Determine 3A exhibits the 3D geological items, which shall be used for eventual Mineral Useful resource estimation. These items are displayed within the cross part introduced in Determine 3A and the map view in Determine 3B.

(B) Plan view displaying related geology and regolith extension by 3D modeling. A yellow hint line signifies the situation of the cross-section displayed in “A.” The black contour represents the delineated curiosity space that has been modeled and the white dots signify drill holes within the space. The picture exhibits that the mineralized horizon (M) discovered at Veronica Norte is managed by the event and conservation of beneficial regolith horizon at sure topographic ranges the place continuity is exhibited. The mineralization is discovered at shallow depths (roughly first 10 – 15 m from the floor).

The yellow hint line signifies the situation of the cross-section displayed in “A.” The black outcrop contour represents the delineated areas of curiosity which were modeled so far.
Sampling and Assay Protocols
The 125 sonic drill holes had been sampled in intervals of 0.8m to 2m, for a complete of 1,827 samples, which had been despatched for TREY evaluation to ALS, and desorption TREY Evaluation to AGS. Sampling and analytical protocols are unchanged from the Penco Technical Report, which was recognized to be in keeping with customary business apply. The QA/QC program signifies excessive ranges of precision and accuracy for Dy, Tb, Nd, Pr and Lu. General, the database for complete grades equally exhibits excessive precision and accuracy.
