Grande Portage Completes LiDAR Survey at Herbert Gold

Property/Commences Awareness Program

VANCOUVER, BC, October 4, 2018 – Grande Por tage Resources Ltd. (TSX-V: “GPG”);

(OTCQB: “GPTRF”); (Frankfurt: “GPB”); (“Grande Portage” or the “Company”) today

announces the completion of a Light Detection and Ranging (LiDAR) survey on the Herbert Gold

Property in SE Alaska. The report was completed on time and on budget by Quantum Spatial of

Corvallis, Oregon. Data were collected to aid the Company in assessing the topographic properties

of the study area and to facilitate the creation of a high quality topographic map to aid in geological

mapping and structural interpretation of the bedrock hosting mineral deposits and in preparation of

future engineering and drill targeting plans.

The topography in the Herbert area is highly expressive of the geologic structure in the underlying

bedrock as a result of the weakening of the rock due to fracturing, faulting, and hydrothermal

alteration and the subsequent selectiv e erosion by glaciation, running water and weather. Previous

topographic maps of the area did not have the resolution to properly interpret many of these

structures, but the new LiDAR maps have extremely high-resolution including the ability to process

and to penetrate through brush and tree cover of highly vegetated areas.

The major mineralized veins occupy east -west linear depressions that can be traced for h undreds of

metres. As well, a myriad of transverse, intersecting and satellite structures are part of the same

mineralizing system, many of which exhibit potential of being mineable entities in their own right.

Mapping and interpretation of structures on the surface is important to understanding the

subsurface geology encountered in the drill holes and will serve as an aid in future resource

calculations. This survey will assist the Company in identifying future drill targets.

The Company is also pleased to announce the comme ncement of its online marketing and

advertising awareness program which wi ll focus on creating investor awareness in Europe and

North America. As such, the Company has retained the services of Stockhouse Publishing Ltd. ,

Howe Street Media Inc. and Winning Media LLC. The Company will receive significant exposure

through content brand insertions in financial and trade media and extensive search engine marketing

over the next 12 months focusing on small cap investors.

About Grande Portage:

Grande Portage Resources Ltd. 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% NSR in

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

NI 43-101 technical report d ated 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, eac h 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 structures 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 identification of major elements of a

complex mesothermal gold-quartz system with numerous targets.
