Among the highlights, the company reported 130.5m grading 2.25g/t gold equivalent, within a broader 392.6m from 80.5m, grading 1.54g/t gold-equivalent or 0.53% copper and 0.41g/t gold.

It follows a set of "terrific" results that prompted a share price plunge last month. 

Yesterday Serengeti fell more than 23% to close at C19.5c, however it has spent much of this year around the 15c mark before spiking to 60c in October following its first assays from Kwanika. 

The results will feed into a new resource model for the Central Zone, and a prefeasibility study due mid-2019 for the project, held by Kwanika Copper Corp (Serengeti 65%; POSCO DAEWOO 35%).

"I'm delighted that the drilling has confirmed what we've suspected for a while; that there's a higher-grade core to the Central Zone porphyry which should allow both the open pit and underground operations to access elevated gold and copper grades early on in the mine plan," Serengeti president and CEO, and KCC president, David Moore said.

The company finished August with C$625,000 (US$466,000) in working capital and said in October it had sufficient cash to fund operations for the next 12 months, with POSCO funding the PFS.

It is capitalised at $18 million.
