Avante Mining Hits Additional Sulfides Over 22 Metres at Voisey’s West

Vancouver, BC, September 12, 2023 - Avante Mining Corp. ("Avante" or the "Company") (TSXV: A V A),

is pleased to announce that it has intersected two additional intervals with visually identified nickel sulphide

including 22 metres and 16 metres containing disseminated to semi-massive sulfides at the V oisey’s West

nickel project (“V oisey’s West” or the “Project”). The Project is located in the same intrusive complex as

the nearby V oisey’s Bay mine and 70km west of the town of Nain, Labrador, Canada.

Highlights

• Two additional holes into new zone containing visually identified nickel sulfide in pyrrhotite.

• Hole 4 contains highest concentration of sulfides to date including large zones of semi-massive

sulfides.

• Hole 5 shows higher percentage of visual copper mineralization indicating potential for platinum

group elements and gold enrichment.

• Drilling continues to expand on new discovery located 950 meters north of drillhole intersection

showing 5 metres at 1.28% nickel, 0.52% copper and 0.03% cobalt (08-LP-55).

• Multiple targets remain open for expansion and show potential for additional new discoveries.

• Magmatic nickel sulphide style of mineralization, similar to the nearby V oisey’s Bay.

Adrian Smith, CEO of the Company commented, “These new holes show the highest concentration of

sulphides on the property that we have seen. We are also seeing a variation of metals with a greater amount

of visible copper higher in the system and greater concentrations of sulfides below, leaving us excited to

follow the mineralization to depth where more massive sulfides could exist. The latest drilling verifies the

presence of favorable conditions for the development of substantial mineral accumulations, and we are

enthusiastic about progressing with our efforts at V oisey's West.”

Continued drilling at V oisey’s West has intersected two additional intervals of disseminated, blebby, net-

textured, sulfide-matrix breccia, semi -massive and massive sulfides. The Company’s Geologists have

visually identified nickel -sulfide in the form of pentlandite and copper -sulfide as chalcopyrite within

pyrrhotite hosted in a gabbroic mafic intrusion.

The Company’s Geologists confirm a magmatic sulfide system is hosted on the V oisey’s West, similar to

the nearby V oisey’s Bay mine. Typical magmatic sulfide textures from the current drilling are shown in

Figures 1 to 4 below and include type examples of net -texture, semi-massive and sulfide- matrix breccia

textures. These are formed as mafic intrusions interact with sulfurous country rock and separate the metals

from the magma during emplacement. The sulfurous country rocks at V oisey’s West are the same

metamorphosed sediments (paragneiss) as at V oisey’s Bay which have proven themselves to be an ideal

source of sulfur to generate large volumes of sulfides. The depth potential of the system is only constrained

by the presence of the sulfur -bearing country rocks, which in the case of V oisey’s West appears to be

significant.

14.5 (top) from 20.5 to 21.5 (middle) and from 19.5 to 20 (bottom).

Holes VW-23-04 and VW-23-05 show that the typical density settling characteristics of a magmatic system

where the hole VW-23-04 drilled at the steepest angle encounters higher sulfide concentrations where hole

VW-23-05 shows higher copper content and greater disseminations and net textures. Due to the vertically

zoned nature of the mineralization, there remains great potential for increased accumulations of sulfides at

depth.

Drill hole VW-23-04 cut an additional zone of visible sulfides at the newly discovered North Baccy Zone

over 22 metre intervals downhole. The mineralized interval consists of gabbroic intrusive rock with sulfides

from 1-2% to predominantly greater than 10% to 20% and to over 60% as disseminations to net -textured

to sulfide-matrix breccia and locally massive. The Company’s Geologists have visually identified nickel

sulfide as pentlandite hosted within pyrrhotite. The gabbro is intruding a garnet paragneiss w hich is

interpreted to be the source of sulfur for the mineralized zone and contains patchy to disseminated sulfides

throughout to the end of the hole at 125 meters. The hole was drilled due north at 60-degree dip.

sulphides with higher concentration of visible copper (chalcopyrite) with visually identified nickel sulfide

and pyrrhotite.

Drill hole VW-23-05 cut additional visible sulfides at the newly discovered North Baccy Zone over a 16-

metre interval. The sulfides are concentrated in the same gabbroic intrusive rock but show higher elevations

of visible copper mineralization as seen in Figure 4. Sulfide concentrations range from 2% to predominantly

10% to over 40% and occur as disseminated, blebs and bands, net -textured, fracture-fill, to semi massive.

Company geologists have visually identified copper and nickel sulfides in the form of chalcopyrite and

pentlandite within the pyrrhotite. The hole was drilled due north at a 45-degree dip.

The Company has now confirmed a magmatic sulfide system hosted on the Project in drilling to 1 kilometer

in length. The project scale geology also suggests that there is a significant vertical zone where the two rock

types responsible for generating nickel sulfides are present, and it is likely that the zone of sulfide generation

extends to depth along the pathways of the mafic intrusions.

Adrian Smith continues, “The evidence from drilling is clear, there is a magmatic sulfide system hosted on

V oisey’s West; the same system type responsible for the nearby world class V oisey’s Bay mine and

occurring in the same geological setting. The new drilling has been key to understanding the controls on

the mineralization and shows the classic vertical settling of sulfides giving us a clear objective to follow

the system to where there are potentially more massive sulfides with higher grades.”

The true thickness is not known, and additional drilling will aim to better define the orientation and extent,

specifically to depth where higher concentration of pooled sulfides may exist, and further north where

additional untested anomalies exist. The Company plans to provide further updates on drilling as additional

information becomes available. Drillers have gone on break with gear remaining at the P roject while the

Company works to log and sample the core . Initial results will be rushed through the l ab for analysis at a

Canadian accredited laboratory for complete multi-element analysis with further updates to follow.

About the Voisey’s West Project

The Voi s ey ’s West is located 50km from, and within the same intrusive complex and geological setting as

the world class V oisey’s Bay nickel mine.

The Project is in the Churchill Province of Labrador and underlain predominately by quartz-feldspathic and

metasedimentary gneisses derived from plutonic and sedimentary rocks. The rocks are intruded by the

multi-phase, Nain Plutonic Suite (NPS) composed primarily of anorthosite, troctolite, diorite and granitoids

and are known to host nickel-sulfide mineralization.

Following the discovery of V oisey’s Bay deposit, enhanced regional prospecting led to the discovery of

three pyrrhotite-chalcopyrite-pyrite-pentlandite showings located on the Voi se y ’s West, namely, the Long

Pond, All-About-It and No Baccy. Initial surface grab samples from the Long Pond and All -About-It

showings returned up to 1.36% Ni ckel and 0.58% C opper, and 1.05% Ni ckel and 1.53% C opper

respectively. Continued work led to the identification of a primary mineralized corridor occurring over

approximately 2.5 kilometres and multiple high-grade nickel drill intersections up to 14 metres of 1.02%

Nickel, 0.51% Copper and 0.03% Cobalt.
