LCL Resources (ASX: LCL ) has received promising results its 100% owned PNG Liamu Gold-Copper Project following completion of LCL’s first reconnaissance trenching and pitting program at the Dada porphyry prospect.
All of the trenches encountered veining and alteration consistent with a large, mineralised porphyry system.
“‘These first results are very encouraging and not only confirm the presence of a large porphyry system at Dada but also highlight the potential size and scale of the mineralisation,” Executive Chairman, Chris van Wijk, said.
“Each of the trenches returned gold mineralisation, and all of the trenches remain open within the broader 0.1g/t gold in soil anomaly. Additionally, two rock samples to the south of the prospect returned 2.19g/t and 1.29g/t respectively which hint at the prospect of higher-grade zones within the porphyry system.
“This programme is the first exploration programme conducted by LCL on the Liamu exploration license and highlights the latent potential within the LCL portfolio of assets. Furthermore, these results are the first to reflect a renewed focus on the Copper-Gold assets within the portfolio. There remain a number of other Copper-Gold opportunities to follow up on in PNG and we are excited to explore the existing targets within the portfolio.’
The LCL field programme was conducted over roughly 400m of strike in the north-south direction with six trenches completed. The Dada gold-copper porphyry prospect forms part of the Liamu Project in PNG.
Historical surface sampling defined a 600m x 400m Au >0.1g/t anomaly, open to the west and coincidental with multiple NE-SW trending elongated Copper anomalies carrying over 500ppm Cu in soils and rock chips.
A previous trench (the Footprint Trench), excavated perpendicular to the NE-SW trend, exposed intense veining (up to 40 veins per metre consisting of ‘A’ and ‘B’ porphyry style veins) over 96m grading Au 0.41g/t within felspar porphyry and diorite. This was not followed up until this recent exploration programme.
In August 2024, LCL completed a trenching and pitting program to test for extensions to the intense porphyry veining and extensions of the gold rock chip anomaly to the west to determine the presence of a near surface causative gold-copper porphyry.
The trenching program targeted six trenches to test gold in soil anomalies along strike from the original Footprint Trench at Dada. The trenching program was helicopter supported and carried out over a 3-week period in August. The trenches were hand dug and then channel sampled with samples being assayed for gold and multi-element geochemistry.
