Comet Resources Ltd (ASX:CRL) has identified numerous mineralised structures at surface in a recent detailed geological mapping campaign of historic drill collars, shafts, and artisanal workings at the Santa Teresa Gold Project in Baja California, Mexico.
Consultants Minera Cascable conducted the mapping program and collected several samples during the survey process, which have been forwarded to ALS Chemex in Hermosillo, where they will be prepared for assaying at ALS Chemex in Vancouver.
Minera Cascabel also conducted a thorough review of the historical drill core from the 2008 diamond drilling program.
Around 27 samples have been cut from old core, which will also be sent to ALS Chemex for multi-spectrum analysis.
This will assist in determining the mineralogy of the gold deposit.
“Pleased with progress”
Managing director Matthew O’Kane said: “I am very pleased with the progress at the Santa Teresa Gold Project.
“Interminco and Minera Cascabel have done a good job of arranging access to the project site with the local stakeholders and have then wasted no time in completing the initial field survey, detailed geological mapping and a review of the historical drill core.
“I am looking forward to receiving the results from the samples sent for assay, and also the completion of the permitting process for drilling.”
Ground magnetic survey to begin
A strong association of the gold with pyrrhotite has been noted in an inspection of the historical drill core, with a significant magnetic signature.
This suggests that a ground magnetics program may be a useful tool to assist to better define targets for the upcoming drilling campaign.
To test this thesis, a small ground magnetics survey will shortly be conducted over areas of known high-grade mineralisation to determine if a magnetic signature coincides with high-grade intersections from the 2008 drill campaign.
Diamond drilling planning underway
Drilling permits will be submitted shortly once final documentation is completed.
Approval is expected within 60 days thereafter, unless delayed by COVID-19-related staff reductions at government offices.
A diamond drilling campaign is being planned based on the historical drilling results combined with the information obtained from fieldwork done to date by Interminco and Minera Cascabel.
Water in old artisanal workings will be used for the drilling campaign.
The workings will then be pumped out, mapped and sampled, which will yield additional information on the location of the mineralised vein structures underground.
Preliminary investigations are also underway to assess the timing and process for the permitting and mining of a small underground exploration shaft that would allow underground drilling platforms to be established.
