Grande Portage Announces Channel Sample Assays of 8.46 OPT

Gold and 6.53 OPT Silver on Herbert’s Goat Vein

VANCOUVER, B.C., October 10, 2018 – Grande Portage Resources Ltd. (TSX-V: “GPG”);

(OTCQB: “GPTRF”); (Frankfurt: “GPB”); (“Grande Portage” or the “Company”) is pleased to

announce gold assay results from two surface channel samples collected from the Goat Vein at its

Herbert Gold project in SE Alaska.

Goat Vein Channel Sample Highlights:

 Channel sample #54524 assayed 129.02 gpt gold (3.76 opt) & 68 gpt silver (1.98 opt)

 Channel sample #54525 assayed 290 gpt gold (8.46 opt) & 224 gpt silver (6.53 opt)

By way of historical background, d uring the 201 7 exploration and drill program a number of

representative grab samples were taken from the Goat Vein assaying up 6.75 opt/gold with 49.8

gpt/silver. (see news release dated September 6 th, 2017 ). Notwithstanding the impressive grade s,

grab samples are not sufficient as an assay contributor to NI 43-101 resource estimates. Therefore,

during the Company’s recently completed 2018 program it sought to include channel samples which

are acceptable for inclusion into resource estimate s. The two 2018 channel samples cut at 90

degrees to the same Goat Vein are located just East of the mid -point of the inferred strike of the

vein where rapid erosion of the stream bottom recently exposed a segment of the resistant

mineralized quartz vein and some of the altered wall rocks.

The Goat Vein currently has an indicated length of over 2300 feet ( 700 meters ) running East to

West, dipping at 75 degrees to the North. Channel #54524 measured approximately 4” x 3” x 1.12

meters true width and assayed 129.02 gpt gold (3.76 opt ) with 68 gpt silver (1.98 opt) . Channel

#54525 was collected 23 feet ( 7 meters ) to the W est, measured approximately 2. 0” x 3” x 1. 02

meters true width and assayed 290 gpt gold (8.46 opt) and 224 gpt silver (6.53 opt). Sample #54525

was processed by ALS Labs using metallic screening for coarse gold, fire assaying and multi element

ICP procedures. Sample #54524 was sent to B ureau Veritas Labs for assay and additional

metallurgical testing, those results are expected shortly. These assays qualify for addition in to future

resource calculations.

Ian Klassen , Grande Portage’s CEO remarked “The continuing confi rmation that the Goat Vein

exploration program yields impressive gold assays reaffirms our commitment to the Herbert Gold

property development. We are delighted to receive these gold assays from the Goat Ve in as

representatively tested at surface. The hig h grade nature of the results further encoura ge us to

believe that the Goat V ein will be as prolific as the Deep Tren ch and Main Veins. W e will begin

About Grande Portage:

Grande Portage Resources L td. is a Tier 2 publicly traded mineral exploration company principally

focused on the Herbert Gold Property situated approximately 25 km north of Juneau, Alaska. The

Company holds a 100% leasehold interest in the Herbert Gold Property, subject to a 5% NS R in

favour of the underlying property owners. The Herbert Gold Property has an amended and restated

NI 43-101 technical report dated July 12, 2018, effective May 28, 2018, completed with an uncut

Indicated Mineral Resource of 1,107,000 tonnes containing 257,950 oz of gold at 7.25 g/t and uncut

Inferred Mineral Resources of 423,200 tonnes containing 82,200 oz of gold at 6.04g/t, each at a 2.5

gpt cut-off. The system is open to length and depth and is host to at least six main composite vein -

fault structur es that contain ribbon structure quartz -sulfide veins. The project lies prominently

within the 160km long Juneau Gold Belt, which has produced nearly seven million ounces of gold.

The results from the Company’s drilling programs confirm the identificatio n of major elements of a

complex mesothermal gold-quartz system with numerous targets.
