The analysis of the diamond drilling at Brigadier Gold [TSXV:BRG], the junior miner exploring in Mexico’s Sinaloa state, has confirmed the company’s high expectation of the site. The first results from last year’s diamond drilling published in January showed that the company intercepted content with 9.49 g of gold per tonne of ore and 24 g/t of silver across 3 metres. Today’s update has provided a clearer idea about the shape of the Picachos vein, showing a seven-kilometre long vein system of precious metals mineralization and adding information on different locations within the project.
In an earlier podcast with the Armchair Trader the company set a high bar in terms of expectations for Picachos, and results so far have not disappointed, proving that what lies beneath the ground is a really rich deposit of gold and silver, with some copper thrown in for good measure. According to the company, “it is only just getting started.”
High grade of consistent precious metals mineralization
The widely spaced holes confirmed that the vein runs continuously and contains a high grade of consistent precious metals mineralization. The diamond drilling also confirmed meaningful gold and silver content in the hanging wall and footwall of the vein systems. It discovered previously unexplored high-grade gold and silver historic workings. The reconnaissance and mapping also showed a number of new surface and subsurface targets. Given the results of the copper porphyry target sampling there is likely to be follow-up exploration later this year.
Brigadier’s chief geologist Michelle Robinson commented: “results of our phase-one program at Picachos imply a robust and geographically expansive mineralized system for which we have only just scratched the surface. I am very pleased with our results, in particular the number of targets demanding follow up drilling or for newly discovered zones, a first ever drill hole.”
In the course of this year the company plans to expand the depth and strike length at its Cocolmeca vein, a persistent and strongly mineralized vein structure at the project.
Brigadier Gold is focusing on several veins
Of the 28 holes drilled so far, fourteen were drilled to test the San Agustín vein, the site of a historic mine, while ten holes tested surface exploration targets. Another two holes explored under the historic San Antoñio mine and one hole tested under La Gloria, also an underground mine which historically produced gold.
Brigadier cut a sample across the south eastern face of the La Gloria stope which returned a result of 49.6 g/t gold and 31 g/t silver across 0.4 metres. Mineralization in the stope consisted of microcrystalline quartz breccia intergrown with pink epidote and native gold along a shear zone hosted in agglomerate.
Palodismo, a small underground prospect north of the entrance to La Gloria was first identified in a historic sample with results of 27.61 g/t gold and 4 g/t silver across 1.3 metres. The notes to the historic sample mentioned pink epidote-quartz. A second underground prospect southeast of La Gloria cross-cut was sampled by Brigadier with results of 9.7 g/t Au and 2 g/t Ag across 0.8 metres.
