Length is not an assay interval
Total hole length describes the drilled path. It is not the length of mineralised rock, vertical depth, true width or evidence of an economic resource. This government layer does not supply assay intervals, so grades and gram-metre products are not inferred here.
Check the original context
The operator and project names are recorded historical labels. Drilling dates are preserved as supplied and may include estimated dates or ranges. Initial inclination and azimuth describe the collar orientation, not the full hole trajectory. Wedge holes may share the parent collar and report length from surface.
Government drill-hole IDs can repeat across source entries. The feature ID above distinguishes this entry without assuming that matching hole IDs are separate physical holes. The source-reference text is reproduced without inventing a report URL. Open the government record and use the cited reference to locate the original report. Read the government field definitions ↗.
