Skeena's CEO, Walter Coles Jr. commented, "Eskay Creek has a rare combination of attributes: scale, impressive grade and location in a tier one mining jurisdiction with strong First Nations support. In the first 5 years of operation, it is anticipated that Eskay Creek will produce, on average, 450,000 gold equivalent ounces per year. We expect further increases to the annual production profile as we move to the Feasibility Study in Q1 of 2022, and beyond. Our goal is to create a mine producing 500,000 gold equivalent ounces per year for 10 years. The PFS is only based on the current open-pit resources. Skeena has a 35,000-metre exploration program underway at Eskay Creek to continue to grow the open-pit resources, and we have yet to focus on the considerable underground exploration potential."

PFS Overview

The 2021 Eskay Creek PFS considers an open-pit mine with on-site treatment of the mined material by conventional milling and flotation to recover a gold-silver concentrate. The mine will be an owner-operated, standard truck and shovel open-pit, with a leased mining fleet. The plant will process ore at a nominal rate of 2.0 million tonnes per year ("Mt/y") (5,480 tpd) in Year 1 during ramp-up, 2.9 Mt/y (7,945 tpd) for Years 2 to 4 then reduce to 2.7 Mt/y (7,400 tpd) in Year 5 onward as the material increases in hardness and competency over an expected production lifespan of 9.8 years. An additional 30 months of pre-stripping, stockpiling and mine access development is planned prior to the processing facility becoming fully operational in Year 1. The PFS leverages Eskay Creek's extensive existing infrastructure, including all-weather access roads, previously permitted tailing storage facilities ("TSF") and proximity to the 195 MW hydroelectric facilities and linked power grid.

The PFS is derived from the Company's pit-constrained resource estimate (April 7, 2021) and does not include results from the recently initiated and ongoing 2021 drill program. The effective date of the PFS is July 22, 2021, and a technical report will be filed on the Company's website and SEDAR within 45 days of this disclosure.

Mining Overview

An open-pit mining only scenario is the basis for this PFS. The underground precious metal resource opportunity has not been considered at this time. The owner-operated, leased mining fleet will utilize conventional truck and shovel methods with 22 m³ shovels and 144 tonne haul trucks. Support equipment is comprised of track dozers, graders, and hydraulic excavators; additional support equipment to maintain production during seasonal periods of high snowfall has also been incorporated.

The mine designs and scheduling were engineered to provide 2.9 Mt per year of ore to the process plant in the first 4 years, followed by 2.7 Mt per year for the remainder of the mine life.

A total of 26.4 Mt of diluted mill feed averaging 3.37 g/t gold and 94 g/t silver (4.57 g/t AuEq), is expected to be processed over the life of mine from the main pit area and a smaller satellite pit hosting the 22 Zone.

Mill feed will be trucked to a primary crusher located to the west of the main pit and then conveyed overland to the processing facility. Non-acid generating waste totaling 161 Mt will be stored in a waste storage facility adjacent to the main and satellite open pits with a portion backfilled into the pit as the mining sequence advances towards the north. Potentially acid-generating waste totaling 50 Mt will be hauled to the Tom MacKay storage facility and stored sub-aqueously together with tailings.

Open-pit mining dilution has been estimated to cause a 21% increase in tonnes delivered to the mill and a 16.6% decrease in overall head grades. Pit slopes were grouped into weak and competent lithology groups. The weak slope domains were applied to the mine design using an inter ramp angle ("IRA") of 34 degrees with recognition of areas that exhibit lower rock quality. A default IRA of 46 degrees is applied throughout for the competent rocks. Batter angles of 70 degrees have been applied throughout the entire design with IRA achieved by variable berm widths.

The reserves for Eskay Creek are based on the conversion of the Measured and Indicated resources within the current Technical Report mine plan. Measured resources are converted to Proven Reserves and Indicated resources are converted directly to Probable Reserves. The total reserves for Eskay Creek are shown in Table 4 below. Some variation may exist due to rounding.

Table 4: 2021 Proven and Probable Reserves (Metric Units)

Reserve Class	Tonnes	Grade			Contained Ounces
	(Mt)	AuEq (g/t)	Au (g/t)	Ag (g/t)	AuEq (Moz)	Au (Moz)	Ag (Moz)
Proven	13.5	5.81	4.25	124	2.53	1.85	53.7
Probable	12.9	3.26	2.46	64	1.35	1.02	26.5
Total	26.4	4.57	3.37	94	3.88	2.87	80.2

Note: This mineral reserve estimate is as of June 30th, 2021 and is based on the mineral resource estimate dated April 7, 2021 for Skeena Resources by SRK Consulting. The mineral reserve calculation was completed under the supervision of Willie Hamilton, P.Eng. of AGP, who is a Qualified Person as defined under NI 43-101. Mineral reserves are stated within the final design pit based on a US$1,475/oz gold price and US$20.00/oz silver price. The NSR cut-off grade of C$30.56/t was used to define the marginal cut-off material. The life-of-mine mining cost averaged C$3.14/t mined, preliminary processing and G&A costs are C$24.50/t ore and C$6.06/t ore respectively. The ore recoveries were varied according to gold head grade and concentrate grades. Gold concentrate grades varied from 20 to 60 g/t gold. The gold equivalent grades are based on 79.3 Ag ounces yielding similar value to an Au ounce.

Production Profile

The PFS outlines an average production profile of 450,000 oz AuEq over the first five years of production. Average annual production over the full LOM is expected to be 352,000 oz AuEq. Further optimization or exploration discoveries may increase the production profile or extend the LOM schedule in the future.

It is anticipated that Skeena will have accumulated approximately 500,000 tonnes of mineralized material on surface when the processing plant is expected to reach its designed throughput capacity, providing flexibility in the early stages of production. This ramp-up profile is expected to lower the risk of start-up and minimizes sustaining capital investment at the outset of the production. There is potential for the ramp up profile to be accelerated with further optimization work.

Metallurgical Optimizations

PFS Test Work

Skeena completed additional Prefeasibility test work in 2020. The samples used in the PFS test program as well as fresh core intervals from the 21A, 21B, 21C, 21E and HW Zones were evaluated by Base Metallurgical Laboratories Ltd. in Kamloops BC. Composite samples representing the first three years of plant feed were also prepared. An extensive flotation testing program was completed, resulting in a modified process flowsheet.

Mineralogical studies indicated a portion of the gold was associated with non-sulphide gangue and flotation performance was negatively influenced by the presence of soft minerals. The solution was to include a desliming stage where these soft minerals were isolated and floated separately. The result was improved flotation response for the coarse material. This mill-float-mill-float circuit ("MF2") is used in platinum processing for fine-grained precious metal recovery.

Improved Metallurgy

The MF2 flowsheet was tested on both the annual composites and variability samples to evaluate its suitability to process a range of Eskay Creek material. The result was the ability to generate a higher concentrate grade without significant loss in gold recovery. This is a significant improvement over the PEA flowsheet.

A 45 g/t Au concentrate is being targeted to maximize gold recovery although samples generated final concentrate grades of more than 55 g/t Au. Concentrate silver grades are expected to be between 900 g/t and 2,400 g/t with the average LOM concentrate grade being 60 g/t AuEq. Arsenic, mercury, and antimony penalties are primarily incurred during the first three years of operation with an average cost of approximately C$18M per year. The highest penalties are incurred in the first year of operation (when the higher gold grade feed is processed). From Year 4 onwards, arsenic in concentrate is expected to be at or below 1% and mercury below 350 ppm.

Processing Overview

Run-of-mine ("ROM") material is trucked from the mine and either stockpiled or direct fed into the primary crusher. Primary crushed feed material is in turn conveyed to the mill facility and stacked onto a coarse ore stockpile. The ROM material is considered relatively competent with average Bond Rod and Ball Mill Work Indices of 15.8 kWh/t and 17.9 kWh/t, respectively. To achieve the target primary particle P80 (80% passing) size of 100 µm the comminution circuit comprises a 3.8 MW semi-autogenous grinding (SAG) mill, 7.3 m diameter by 4.3 m effective grinding length, and a 4.9 MW ball mill, 5.5 m diameter by 9.0 m length. A pebble crushing circuit is also included and will be commissioned in year 4. Ground material is processed through a split flotation circuit consisting of roughers, scavengers, fines roughers, cleaners and fines cleaner flotation, along with regrinding of rougher concentrate, slimes classification of rougher tailings and secondary grinding prior to scavenger flotation. Rougher concentrate is re-ground to a target P80 size of 15 µm and slimes classification underflow is secondary ground to a target P80 size of 30 µm, prior to multiple stages of cleaning to produce a combined gold-silver concentrate with the slimes circuit concentrate. Flotation tailings are pumped to the existing Tom MacKay Storage Facility and sub-aqueously stored together with the potentially acid generating ("PAG") waste rock. Flotation concentrate is thickened and filtered, and trucked to the port at Stewart, BC for loading onto ships and transportation to third-party smelters worldwide.

Concentrate Marketing Studies

Multiple marketing assessments have been completed to support the PFS which indicate that the Eskay Creek concentrate is readily saleable at a target grade of 45 g/t Au. The preferred preliminary contract terms for the concentrate have been provided by Asian smelters, however multiple offtakes are available. Smelters/traders within Europe have also provided draft term sheets, and these have also been identified as potential markets given the high concentrate grades. The Company has been offered several preliminary term sheets for the entire concentrate production, which have been used as the basis for the financial model, and include gold and silver payabilities, industry standard treatment and refining charges, and penalties for impurities. For the purposes of the PFS, smelter payabilities average 84% for gold and 83% for silver.

Environmental and Permitting Considerations

Eskay Creek represents a closed mine with existing permits for mine disturbance and development, mine discharge and waste disposal. The site has been maintained in good standing and environmental monitoring has been ongoing during operations and since the site was closed in 2008. There is a substantial database of environmental information for the site and region spanning almost 30 years. To accommodate the mine design contemplated by the PFS, updated environmental assessment and mine permits will be required. The Company is completing environmental and socio-economic baseline studies and recently entered the environmental assessment and permitting process.

Eskay Creek is projected to be one of lowest GHG emission open-pit gold mines worldwide, emitting an average of 0.18 tonnes of CO₂e per gold equivalent ounce produced. Several factors contribute to this low number, such as the high-grade nature of the deposit and access to clean, green hydro energy near the site.

Skeena is committed to a further reduction in GHG emissions and is actively working on several initiatives to further reduce emissions, which include:

• Electrification of mine mobile equipment, including shovels, drills, excavators, personnel carriers, and snow removal equipment
• Electrification of all stationary mine equipment, including mine dewatering pumps and pit lighting etc.
• Conversation of the heating of the main facilities such as buildings, camps, administrative, mine offices, plant, and lab buildings from propane to electric.
• Electrification of the transportation of waste from diesel haul trucks to electric overland conveyor systems.

Community Relations

The Project is within the traditional territory of the Tahltan Nation. Eskay Creek has maintained a long-standing relationship with the Tahltan Nation. Previous operators maintained agreements with the Tahltan which included provisions for training, employment, and contracting opportunities. The Company has been working in the Tahltan Territory since 2016 and has developed a strong working relationship with the Nation. Skeena also maintains formal agreements with the Tahltan Central Government which guide communications, environmental practices, and contracting and employment opportunities for projects in Tahltan Territory. Skeena participates in the BC Regional Mining Alliance (BCRMA) which is a partnership between First Nations, the BC Government, AME BC and exploration companies operating in the Golden Triangle region of BC. The BCRMA provides a platform for all parties to collaborate in communications with potential investment partners on opportunities in the region.

Tsetsaut/Skii km Lax Ha Nation has asserted traditional land use in the area of Eskay Creek. Skeena has ongoing engagement with Tsetsaut/Skii km Lax Ha who have expressed interest in business and contracting opportunities associated with the Project.

Highway 37 and 37a and the Port of Stewart will be used for Project Shipping. These facilities lie within the traditional territory of the Gitanyow Nation and the Nass and Nass Wildlife Area defined in the Nisga'a Final Agreement. Skeena has carried out initial engagement with the Gitanyow Hereditary Chiefs office and the Nisga'a Lisims Government regarding planned future use of these facilities.

In preparation for the assessment and permitting process, Skeena has initiated early engagement work with regional stakeholders. Early engagement information sessions have been carried out with the Municipality of Terrace and the Kitimat Stikine Regional District. Additional engagement opportunities with other regional stakeholders will commence shortly. For more information, please visit https://skeenaeskaycreek.com/.

Project Opportunities and Value Enhancements

The 2021 PFS clearly demonstrates that Eskay Creek has the potential to be is an economically viable project and tier one operation.

Additional opportunities and next steps include:

• Continued drill conversion of Inferred resources to the Measured and Indicated categories plus ongoing exploration drilling across the Project
• Mine scheduling and downstream investigations allowing for the further optimization of various blending scenarios
• Throughput optimization studies to potentially increase process plant throughput
• Supplementary geometallurgical modelling to further improve metallurgical performance
• Geotechnical investigations to complement and potentially enhance the current pit slope designs
• Investigation of the potential of ore sorting technology to improve plant head grade and reject waste material
• Commercial discussion with potential concentrate off takers to increase payabilities
• Opportunities to include additional feed sources
