Litchfield nails 200m NT copper-zinc mineralisation
The latest result builds on the company’s previous drilling successes and points to a laterally wide corridor that appears likely to expand further.
The thick intersection shows continuity of the system and aligns with metal zoning patterns that can lead explorers to richer copper centers in similar folded landscapes.
The consistent mineralization trend over significant widths indicates a durable, laterally persistent mineralized system; The zinc-dominated signature in the hole reflects a geological and geochemical zonation likely associated with folding and metal remobilization along the Oonagalabi corridor.
Located 170m north of a previous hole that also intersected strong copper grades, the latest result extends the inferred mineral strike distance at Oonagalabi to the north by approximately 300m and adds at least 180m of vertical extension.
Integrated modeling of Litchfield’s induced polarization (IP) data in 2D and 3D provides the first insight into the slope of the corridor with all drilling to date, but fold repeats and precise geometry remain to be fully resolved.
The required solution is being addressed through planned further targeted drilling into bracket fold spacing, improvement of actual thicknesses and pinpointing of the highest grade sections of the main Oonagalabi zone.
Litchfield’s next steps at Oonagalabi include plans for a go-out hole located approximately 450-500 meters south of the company’s most recent main hole in November to investigate structural and mineralization continuity.
A positive outcome from the proposed drilling could potentially identify a consistent high-grade trend extending across an almost 600m strike and significantly increase the resource potential of the project.
Complementing the Oonagalabi core area, an RC drill hole drilled in the southern portion of the Bomb Diggity field, approximately 1.6 km northeast of Oonagalabi – and still within the ~3 kilometer by 0.5 kilometer mineralized Bomb Diggity footprint – intersected thinly dispersed chalcopyrite, pyrite and pyrrhotite in the upper 40 metres.
The sulfur emission underscores the fertility of the region, consistent with magnetic, gravitational and conductivity anomalies that suggest a mineralized intrusive center channeling metal-rich fluids.
Geologically, Bomb Diggity reflects what would be expected from a mineralized intrusive body surrounded by a conductive sulphide halo, which may also offer localized feeder structures and a direction for exploration into thicker and/or higher-grade accumulations along contacts.
Both RC holes placed at Bomb Diggity to date have become steep during drilling and therefore missed the primary magnetic target, but sulphide traces still confirm the geophysical model.
Litchfield’s next steps at Bomb Diggity will prioritize versatile time-domain electromagnetic geophysical (VTEM) plate modeling to improve the geometry of conductive plates displaying sulfides, allowing the company to better identify sulfide targets for future drilling.
Other steps in the project will include high-resolution IP geophysical surveys starting on November 2, followed by ground electromagnetics in mid-November to define conductor extents, feeder zones, and intrusive margins.
The research will refine targets for future drilling to explore for thicker, higher-grade copper-zinc sulphides.
Operationally, with the arrival of the Bullion Drilling, further drilling is planned for early to mid-November, including four additional holes to complete the initial program.
Priorities will include expanding the main Oonagalabi area and testing other north-east conductors that were inaccessible to previous operators, as well as the VT2 VTEM target, 1.7 km east-southeast of Oonagalabi, using new downhole electromagnetic (DHEM) data.
Analyzes for another hole in the northern third of the emerging Oonagalabi formation are expected to be completed in approximately 10 days, while down-hole electromagnetic (DHEM) results will also come from the company’s VT1 VTEM target, 4.5 km southwest of Oonagalabi. On October 23, Litchfield announced an intersection with sulphides on the 400 m long VT1 conductor.
Management’s rapid execution of initial drilling at Oonagalabi has revealed a number of interesting targets with strong expansion potential, highlighting multiple and sometimes broadly similar mineralized systems.
Future initiatives, particularly using geophysics, are expected to further reveal the complexity of Oonagalabi’s folded geology, allowing the company’s next drilling campaign to identify thicker and/or higher-grade zones and outline any exploration potential that may be hidden at depth.
