Grid will be the initial manager of the exploration activities and utilize its exploration team as

required to undertake the initial programs. A technical committee will be utilized to plan,

oversee, and complete the exploration programs. Provided that Boliden exercises the Option, a

contractual joint venture (the “Joint Venture”) will be formed between Grid and Boliden.

Thereafter, each Party would fund its pro -rata share of future expenditures on the Property or

incur dilution. The Agreement contains other standard terms for an option and joint venture

agreement including terms regarding replacement of the operator, sale of a participant interest

and the right of first refusal of the other party, a funding deferral for Grid after the Option has

been exercised, and dilution clauses. During the joint venture period, the party with the majority

interest has the right to become or designate the operator , and i f Boliden arranges project

financing for the project, it has the right to purchase a share of Grid’s offtake proportional to the

percentage of project financing that is being funded.

If a party’s interest in the Property is diluted below 10%, its interest would be converted to a

1.0% Net Smelter Return royalty on the Property, of which 0. 5% could be bought back by the

royalty payor at any time following the fifth anniversary of commercial production f or a cash

payment of CAD$1,000,000.

The Thompson East Copper/Nickel Project

The Thompson East project has a unique combination of attributes that make it prospective for

high-tenor, copper- and PGE-enriched magmatic sulphide deposits. Key features include:

1) The geological setting is at the margin of the Superior Craton where globally significant

base metal deposits occur.

2) Thompson East may be the copper- and PGE-rich ‘cousin’ to the Thompson Nickel Belt

(itself a world class belt) which is located 20 km to the west.

3) The belt is significantly underexplored compared to the nearby Thompson Nickel Belt.

4) There are numerous, significant base and precious metal occurrences on the Property.

5) Work done by Grid has identified several near-surface, strong conductors associated

with good outcropping copper, nickel, PGM, and gold mineralization.

6) Access to, and infrastructure for the project are very good and continue to improve with

upgrades to the rail line to the Port of Churchill and to the Port handling facilities – all of

which would support low-cost shipping of future project concentrate to Europe.

Detailed Project and Geological Description

The Thompson East Property currently comprises two mineral exploration licenses (MELs)

totalling 10,600 hectares. The licenses are located between 30 and 40 km from the City of

Thompson in north -central Manitoba. An additional seven (7) MELs capturing ap proximately

46,500 hectares were recently applied for (status is 'pending'). The property covers several

historical disseminated to massive magmatic sulfide occurrences associated with deformed mafic

and ultramafic intrusive rocks all with extremely limited drilling. Recent confirmatory field

sampling by Grid returned similar favourable grab sample base and precious metal grades to

those seen in the historical samples from the Property. Some of the new grab samples occur within

ultramafic bodies that are known to be coeval with the ultramafic intrusives that host the

numerous high-grade massive nickel sulfide deposits in the adjacent Thompson Nickel Belt (TNB).

The TNB is a world class nickel sulfide mining district that hosts the Thompson Mine, which has

been in continuous production since 1961.

A key similarity between the Thompson East mafic to ultramafic magmatic belt (herein referred

to as the 'TEMB') and the TNB is the character of their highly deformed and high metamorphic

grade sedimentary host rocks. In both belts, the mafic-ultramafic intrusions that host the known

magmatic sulfide deposits and occurrences were emplaced into a former rifted continental

margin containing sedimentary sequences featuring sulfur -rich shales and iron formation. The

host sediments were subsequently intensely deformed and recrystallized at high temperatures to

generate a sequence of paragneiss units. The S -rich members of these sedimentary sequences

are believed to have provided a critical source of sulfur that promoted the formation of magmatic

sulfides in both belts. In the TNB, the paragneiss host rocks are referred to as the Pipe Formation.

A key difference between the two belts is the high Cu and PGE tenors of the TEMB occurrences

relative to those in the TNB, which are strongly enriched in nickel relative to Cu and typically have

very low PGE grades. Examples of high tenor mineralization in the TEMB include: (1) local Cu- and

PGE-rich semi-massive sulfide mineralization such as the Murray Island showing on Wintering

Lake, that contains up to 5.2% Cu, 1.3% Ni, 2.05 g/t Pd, 1.53 g/t Pt and 2.0 g/t Au (Manitoba

Mines Branch Assessment File Num ber 94320); and, (2) Disseminated sulfide mineralization at

the margins of a major dyke -like ultramafic intrusion at Cuthbert Lake, with peak grades of >1%

Cu, >1% Ni , 2.29 g/t Pd, 1.26 g/t Pt and 0.63 g/t Rh (Manitoba Mines Branch Assessment File

Number 73740). Sampling completed by the Company last fall confirmed the high Cu and precious

metal tenors of the Wintering and Cuthbert Lake magmatic sulfide occurrences (see Table 1). Of

particular interest is the high Au and Pt tenor of the magmatic sulfide occurrences at Cuthbert

Lake.

The prevailing geological concept for the TEMB involves a proto -rift basin located inboard from

the TNB and formed during the same magmatic event that produced the TNB mafic and

ultramafic intrusives. In this sense, the TEMB is considered to represent the more deeply eroded

'roots' to the TNB magmatism. Taken together, the two belts represent the westernmost edge of

the continental-scale Superior Boundary Zone. The latter also hosts the Company's Fox River Belt

licenses in northeastern Manitoba, the curr ently producing nickel sulfide deposits in the Raglan

Camp in northern Quebec, and a number of advanced exploration stage magmatic sulfide

deposits in the Labrador Trough on the eastern margin of the Superior Craton.

In 2022, the Company completed an airborne EM + magnetic survey over the two existing MELs.

Subsequent modeling of the data identified several previously untested, near -surface, strongly

conductive anomalies associated with known magmatic sulfide mineralization and/or prospective

mafic-ultramafic bodies.

Despite its excellent geological pedigree, known similarities to the TNB, very favourable access

and significant infrastructure (e.g., major rail line and hydro power transmission lines pass thru

the Property), the Property has seen very limited historical exploration activity.

Initial Exploration Plans

Initial exploration activities being considered for the Property include: (1) new airborne EM and

magnetic surveys over parts of the new MELs, assuming they are approved by the Crown; (2)

detailed prospecting and sampling over priority geophysical targets; (3) Deep penetrating ground

EM surveys over the top-ranked airborne EM anomalies. The ground EM surveys do not require

an exploration work permit as was recently determined by the Manitoba Mines Branch Permit

Office. Given the large amount of geophysical surveying and field work planned, an initial drilling

campaign, focused on the highest-ranked targets, is unlikely to occur until later next year.
