Tres Estados Resource Estimation using Excel template, page-185

More research and thought required mate. The intervals between samples are not barren, they're unsampled. They've only assayed 50 drill samples. Every sample tested is mineralised.

From the other thread:

Intervals without annotation have not been tested due to the labour intensive nature of the previous method used before they developed the new assay method. The new assay method will test all holes from top to bottom.

A few crucial aspects that guide the resource estimate are:-

• Mineralisation is outcropping, widespread, DISSEMINATED and pervasive, independent of rocktype in intense hydrothermally altered kilometre-scale mafic and felsic porphyry intrusions;
• This means that there are no structural controls constraining the mineralised volume;
• No barren rock encountered in drilling or rock chip bulk samples;
