The highest-grade hole Cabral has ever drilled — and it's not in the resource yet

Cabral Gold drilled a hole at its Cuiú Cuiú project in northern Brazil and hit 9.5 metres grading 87.4 grams of gold per tonne — including a 2.9-metre stretch running 285.5 grams per tonne. For scale: most gold mines operate on ore carrying one to a few grams per tonne. CEO Alan Carter says the company has never encountered results of this magnitude anywhere in the district, and Cabral has been drilling Cuiú Cuiú for years. The hole, DDH372, sits at a target called Jerimum Cima, three kilometres from the company’s Central deposit — and, importantly, entirely outside the existing resource base. A second hole reported the same day, 500 metres further east, returned more modest intercepts of 6.1 metres at 0.55 g/t and 13.9 metres at 0.73 g/t.

Why it matters comes down to gram-metre math — width times grade. DDH372 works out to roughly 830 gram-metres; a junior explorer will often celebrate 100. And this hole doesn’t stand alone: an earlier hole 30 metres west cut 45.6 metres at 4.5 g/t (about 205 gram-metres), and another 80 metres east cut 9.5 metres at 5.74 g/t. Together they suggest a high-grade core running at least 110 metres along the structure, inside a broader mineralized envelope the company describes as up to 200 metres wide and at least 750 metres long — open in both directions and at depth. None of this is counted in Cuiú Cuiú’s current NI 43-101 resource, which already totals roughly 450,000 indicated ounces in fresh rock plus oxide material on top.

What to watch: assays from two more Jerimum Cima holes are pending, and drilling is continuing to size both the broader system and the high-grade zone. Three honest caveats. First, the company notes true widths may be only 50% of the reported intervals. Second, the arithmetic inside the headline number: nearly all the gold in that 9.5-metre intercept sits in the 2.9-metre core — the remaining 6.6 metres average roughly 0.36 g/t. Grade that concentrated needs repetition in follow-up holes before anyone can call it continuous. Third, by the company’s own description the drilling here is still early-stage and widely spaced. One spectacular hole starts a story; it doesn’t finish one.
