Sampling And Aerial Survey Defines New Potential At Copper Duke
Titan Minerals Limited (ASX: TTM) has identified a range of exciting new targets from the results of surface geochemistry sampling and initial results for the aerial geophysical survey at the Copper Duke Project located in southern Ecuador, and 18km east of the company’s flagship Dynasty Gold Project.
The new surface geochemistry reports from Copper Duke totals an additional 925 assay results incorporated into the database from the ongoing mapping and, concurrent validating and updating of recent exploration results. The results continue to highlight significant extensions of known copper anomalism across the Copper Duke Project as the footprint of geochemical coverage expands, and the results identify several new high-grade gold quartz veins that potentially represent additional exploration targets for evaluation.
This most recent update to the database represents the first time all geochemical and geology datasets for the Copper Duke Project have been systematically integrated into a single database structure. Our team now has the unprecedented opportunity to interrogate all available data in a digital environment, in conjunction with the newly acquired aerial magnetic and radiometric data.
Within the sampling corridor, several anomalous zones are within a 1.2km proximity to the historical United Nations programme drilling completed in 1978. The recent results indicate potential for a 2km long northwest striking corridor of gold and copper anomalism of significant widths, extending southeast from the historical drilling.
The 2km long anomalous corridor in the northwest of the El Huato anomaly includes several zones of favourable anomalism associated with an interpreted intrusion contact mapped from the recent geophysical results.
Significant intercept results in this corridor, located 1.2km southeast of the UN drill location include 27m of linear sampling, with a mapped width at surface of 15.3m averaging 1.13g/t gold.
The recent sampling also identified several new high grade gold veins located at various locations across the project. Additional sampling and detailed mapping will be required to assess the potential of these targets.
The significant extent of mineralised quartz veining in several areas across the project area is encouraging for conceptually targeting large scale porphyry systems. The density of veining in some areas also provides potential for high grade gold mineralisation targets within the porphyry field.
In late October, Titan mobilised a geophysical crew to complete a helicopter borne, high resolution magnetic and radiometric survey on 100m line spacing across the Copper Duke Project area, immediately following completion of the Dynasty project geophysical survey.
Interpretive results for the aerial geophysical survey have been received for the Copper Duke Project. Several high priority targets for immediate follow-up are clearly defined. Follow-up work includes soil grids over geophysical anomalies to better assess scale and tenor of targets, concurrent with mapping projects to confirm updated geological interpretation. The ongoing field work will provide additional data for ranking of targets for maiden drill testing.
Copper Duke drill planning is now underway and expected to commence Q2 2021 with priority targets located around the historic UN drillholes with reported intersections of:
- 33.1m @ 2.5g/t gold, 154ppm copper, and 2.4ppm Mo, from 9m drill depth and 8.4m @ 1.9g/t gold, 294ppm copper, and 3.9ppm Mo, from 45.3m
- 45.4m @ 1.9g/t gold, 168ppm copper, 3ppm Mo, from surface and 10.9m @ 1.7g/t gold, 857ppm copper, 2ppm Mo, from 51.85m
