High Grade Gold at-Surface Mineralization Discovery
The Linderos Project is an early-intermediate stage exploration project 100% held by Titan Minerals, with high grade epithermal gold and porphyry style copper-gold mineralisation confirmed by drilling.
The Project is located 20km west of Dynasty and comprises 4 contiguous concessions for a total area of 143km2, with all concessions fully permitted for exploration and small-scale mining.
Soil geochemistry and magnetic/ radiometric geophysical surveys have highlighted the presence of multiple porphyry centres across the project, with evidence for shallow epithermal gold systems also observed in surface mapping and geochemistry.
The Linderos Project is largely underexplored, with the Copper Ridge Porphyry and Meseta Gold prospects being the most advanced.
In 2022 Titan completed a maiden drilling campaign at Copper Ridge, successfully confirming broad zones of porphyry copper-gold mineralisation from very shallow depths to approximately 500m vertical. Copper Ridge has significant scope to grow with porphyry copper-gold mineralisation open in several directions.
The Meseta Gold prospect sits adjacent to the Copper Ridge Porphyry prospect, and in late 2022 Titan completed a maiden drilling campaign which successfully returned several wide high grade epithermal gold intersections from shallow depths.
Further work planned at the Linderos Project in 2023 includes an Induced Polarisation (IP) geophysical survey and a second phase of drilling to test extensions to porphyry and epithermal mineralisation at the Copper Ridge and Meseta Gold prospects.
A pipeline of high priority targets are set to feature in exploration work programs in 2023.
In 2022 Titan completed a maiden drilling campaign at the Linderos Project following receipt of all required permits. Gaining all approvals and permits for drilling (including water extraction) is considered a significant milestone in Titan’s exploration activities at the project.
The Copper Ridge Porphyry prospect features surface copper-molybdenum anomalism highlighted by channel and soil sampling recently completed by Titan. Mapping has confirmed copper-molybdenum mineralisation to be centred on dioritic porphyry intrusions approximately one kilometre in diameter, with these porphyritic intrusions also containing abundant A+B veinlets and copper oxide mineralisation at surface.
Eight diamond holes for 3,702 metres were completed in late 2022 to test the potential scale and grade of porphyry mineralisation at Copper Ridge, with drilling confirming the presence of wide intervals of copper-molybdenum±gold±silver mineralisation from shallow depths to ~500m vertical.
Mineralisation is hosted within a diorite porphyry, with vein hosted and disseminated chalcopyrite-pyrite-pyrrhotite-molybdenite, and secondary biotite plus green-grey sericite and pervasive quartz-alkali feldspar defining an early to transitional potassic alteration.
Copper Ridge significant results include:
Importantly, six out of eight diamond drillholes ended in mineralisation, highlighting strong potential for both lateral and depth extensions.
Evidence that Copper Ridge has the potential to host higher-grade copper and gold porphyry mineralisation is supported by intersections including 76m grading 0.5% Cu Eq from 132m in CRDD22-003 and 22m grading 0.5% Cu Eq from 524m in CRDD22-006, returned from Titan’s 2022 drilling campaign.
Further surface mapping and trench sampling is being undertaken to consolidate the understanding of porphyry mineralisation controls at Copper Ridge, and to align surface mapping with logging of recently completed diamond drilling.
Petrographic analysis is planned to determine detailed alteration mineral assemblages and to understand the relationship with associated sulphide occurrences. A selection of representative units will be been sent for age dating to determine the ages of intrusive units and mineralisation events.
An Induced Polarisation (IP) geophysical survey is set to commence in Q2 2023. Aimed at mapping subsurface sulphide mineralisation, the results of the IP survey will be used to inform and optimised the design of Titan’s next phase of drilling at Copper Ride and Meseta.
To the immediate northeast of Copper Ridge, the Meseta Gold prospect hosts gold mineralisation in steep to sub-vertical structures at the margins of the porphyry stock, associated with strong silicification and oxidation of sulphides.
High-grade epithermal gold mineralisation was identified at Meseta in 2017, when artisanal workings on a break-away slope were sampled. The slope exposes a stockwork of oxidised veinlets capped by transported boulders forming a plateau of perched alluvial sediments. The thin alluvial cap covers mineralisation and alteration in the area forming a geochemically blind target beneath a few metres of transported material.
In 2018, diamond drilling confirmed higher grade gold mineralisation in fresh rock, with all drill holes intersected extensive hydrothermal alteration and localised gold mineralisation.
In late 2022 Titan completed 14 holes for 1,270m of diamond drilling, with drilling designed to test the presence of plunging high-grade ore shoots at interpreted structural intersections. Multiple, massive sulphide (pyrite-sphalerite-arsenopyrite±galena) veins were intersected in 12 of the 14 holes, with pervasive phyllic (quartz-paragonite±pyrite), grading to intermediate argillic (paragonite-illite) alteration observed.
The best intersections were returned from an area that has never previously been drilled:
Gold-silver and copper-zinc-lead mineralisation occurs in massive sulphide polymetallic veins that infill shear zones, with vein thicknesses ranging from 0.3 to 1.65m.
Wall rock mineralisation includes disseminated sulphides, ranging from 1 to 20% pyrite, 0.5 to 8% arsenopyrite, 1 to 5% sphalerite, including several zones of 0.5 to 10% disseminated pyrrhotite, and isolated intervals of 0.5 to 2% chalcopyrite, and 0.5 to 1% galena.
