Vancouver, British Columbia--(Newsfile Corp. - July 28, 2020) -  Grande Portage Resources Ltd. (TSXV: GPG) (OTCQB: GPTRF) (FSE: GPB); ("Grande Portage" or "the Company") is pleased to announce that its 2ND drill rig is on site and turning at the Herbert gold property located S.E Alaska. This rig, operated by Alaska Earth Sciences, is currently set up on Pad U which will test unexplored areas of the Deep Trench and Main Veins.

The first rig is drilling long holes on the eastern extension of the Goat, Ridge and Main veins and is advancing as planned.

As well, the Company is pleased to report that early-season surface exploration by geologists has identified at least two quartz vein outcrops of the North Vein which will now be trenched and channel sampled. A majority of this vein is covered by some overburden but the fault and its topographic expression can be traced for over 500 meters.

The North Vein, which only has two drill holes testing it to date, is the northernmost vein of the set of parallel veins comprised of the Goat, Main Vein, and Deep Trench, all of which have significant amounts of associated gold. This vein will be tested by two more drill holes this season from the T Pad.

Assay turnaround times

The Company currently estimates five to seven weeks for turnaround of assay results following completion of a drill hole. This time is required to complete core logging, core sampling, transport to the assay lab, assaying, and subsequent QA/QC (quality assurance/quality control) validation and check assays. Interested parties are cautioned that significant delays may occur due to backlogs at the lab and possible quality control issues identified by the lab, or the company, with particular samples.
