Other standout intervals included a 1.8m intersection at 2.23gpt gold and a 1.1m intersection at 4.1gpt gold.
Across the entire hole, which was drilled to a depth of 130.2m, the overall grade was 0.59gpt gold.
Seven shallow holes were completed at the prospect and the rig was moved to another nearby drill pad to test deeper targets.
"All five holes analysed to date at the Tekem prospect have returned potentially economic gold intercepts within a broad zone of lower grade mineralisation," Quintessential managing director Paige McNeil said.
"The assays are continuing to demonstrate near-surface, primary higher grade gold mineralisation."
Before Quintessential's recent drilling campaign, the Tekem deposit hosted inferred resources of 35,400 ounces of gold grading 2.05gpt.
