Arch Resources to Announce Third Quarter 2022 Results on October 27

 Nickel Creek Platinum Corp. (TSX: NCP) (OTCQB: NCPCF) ("Nickel Creek" or the "Company") is pleased to announce the results of a positive pre-feasibility study ("PFS") at its 100%-owned Nickel Shäw Project (the "Project") located in the Yukon Canada. The PFS has been prepared by AGP Consultants Inc. ("AGP"). The estimated Project after-tax net present value ("NPV") at a 5% discount rate is $143 million with an after-tax internal rate of return ("IRR") of 5.8%. All dollars are expressed in Canadian dollars unless otherwise stated.

Stuart Harshaw , President and CEO of Nickel Creek commented: "The PFS is an important milestone in realizing the opportunity the Nickel Shäw Project represents in the critical mineral space where it can provide nickel and copper to take advantage of the strong nickel market for EV batteries. The sensitivity to energy costs illustrates how working with the different levels of government can lead to a significant improvement in value, especially when combined with the previously announced intention of the Federal government to provide a tax incentive for critical mineral projects such as Nickel Shäw.  Moving forward, our focus will be to continue to add value to the project through work on identified key economic areas of opportunity and continued mineral exploration success while advancing towards a feasibility study."

• $143 million after-tax NPV using a 5% discount rate and an IRR of 5.8% at the following commodity prices: nickel - US$11.00 /pound ("lb"); copper – US$4.00 /lb; palladium – US$2,100 /troy ounce ("troy oz"); platinum – US$1,000 /troy oz; cobalt – US$23 /lb; and gold – US$1,800 /troy oz, each using a 0.75 Canadian to US exchange rate.
• Life of mine ("LOM") after-tax cash flow of approximately $1.7 billion with an after-tax payback period of 12.7 years.
• Pre-production capital cost of approximately $1.7 billion , with a construction period of 3.0 years.

• If paying Yukon grid rates of $0.11 /kWhr, the after-tax NPV at a 5% discount rate increases by $324 million to $467 million (see NPV sensitivities section below for additional information).
• The Company's after-tax NPV at a 5% discount rate increases from $143 million to $336 million if the Canadian tax incentive for critical mineral companies is enacted (see Investment Tax Credit for Clean Technology Manufacturing section below for additional information).
• The Company plans to further investigate the opportunity of carbon tax offsets associated with carbon sequestration in the tailings facility with ongoing testwork and analysis.

On June 1, 2023 , the Company announced an updated mineral resource estimate with an effective date of April 3, 2023 :

The Company's flagship asset is its 100%-owned Nickel Shäw Ni-Cu-Co-PGM Project, located in southwestern Yukon, Canada . The Nickel Shäw Project contains the Company's core Ni-Cu-Co-PGM Wellgreen deposit, as well as the Arch, Burwash, Formula, Musk and Quill claims. The Wellgreen deposit is a polymetallic deposit with mineralization that includes the significant co-occurrence of nickel, copper, cobalt, platinum group metals ("PGMs") and gold.

The Nickel Shäw property contains an extensive Ni-Cu-Co-PGM mineralized system hosted by mafic/ultramafic intrusions related to Triassic-age flood basalts. With over 2.4 billion pounds of nickel, 1.2 billion pounds of copper, 6.9 million ounces of PGMs and 137 million pounds of cobalt in the measured and indicated mineral resource categories, Nickel Shäw is one of the largest undeveloped nickel projects in North America not controlled by a major mining company.

The PFS contemplates that the Nickel Shäw open pit would be mined using conventional open pit methods, with a LOM of over 19 years. From the open pit the ore would be trucked to a primary crusher located adjacent to the pit and conveyed out of the valley to a concentrator designed to process 45,000 tonnes per day ("tpd") of ore. The ore would be fed into a conventional Ni-Cu-PGM flotation concentrator designed to produce a bulk Ni-Cu-PGM concentrate "Bulk conc" or alternatively into split concentrates. The split concentrates would be a Ni concentrate "Ni conc" and a Cu concentrate "Cu conc", as economics dictate. Average annual LOM concentrates production ("dmt") is expected to be 103,100 dmt of Bulk conc, 95,000 dmt of Ni conc and 19,600 of dmt Cu conc. Total LOM payable metal production includes the following:

• 614.3M lbs nickel;
• 281.5M lbs copper;
• 21.5 M lbs cobalt;
• 626,500 troy ounces platinum;
• 743,400 troy ounces palladium; and
• 174,400 troy ounces gold.

The tailings would be stored in a tailings storage facility adjacent to the concentrator. Concentrate would be transported by truck 480 km to the Port of Skagway Ore Terminal. Power will be primarily sourced from a liquified natural gas ("LNG") power plant.

The Nickel Shäw Project lies within the Kluane First Nation ("KFN") core area as defined under the Umbrella Final Agreement between the Government of Canada , Government of Yukon and the Council of Yukon First Nations. Effective August 1, 2012 , an Exploration Cooperation Agreement was signed between the KFN and the Company. The KFN and the government of the Yukon Territory have provided very good support for the Nickel Shäw Project.

Ultramafic rocks from the project (in the form of tailings and waste rock) are being assessed for their ability to capture and store carbon. Test work conducted in 2022 confirmed the presence of brucite (a magnesium-rich mineral known to react quickly with CO2 in air) in a subset of samples. On a mass basis, from the achieved reactivity in the testwork, this may enable maximum sequestration of 2.1 kt CO2 per Mt tailings. The Company is evaluating further work which will include the creation of a mineralogy model based on the project's geochemical database to assess the spatial distribution of rocks within the Wellgreen deposit that have high potential to sequester carbon (see news release dated December 15, 2022 for additional details).

Based on the assumed commodity prices noted above, the LOM revenue by metal is as follows: nickel – 62%; palladium – 14%; copper – 10%; platinum 6%; cobalt – 5% and gold – 3%.

The discount rate sensitivity is as follows:

The after-tax NPV ($Million's) at a 5% discount rate:

The pre-tax and after-tax NPV ($Million's) at a 5% discount rate:

The Canadian 2023 federal budget proposed the introduction of a 30% refundable investment tax credit for investments in eligible property associated with eligible activities for clean technology manufacturing and processing, as well as critical mineral extraction and processing (the "Clean ITC"). The Clean ITC would apply to investments in certain depreciable property that is used all or substantially all for eligible activities. This would generally include machinery and equipment, including certain industrial vehicles and related control systems used in manufacturing, processing or critical mineral extraction. A portion of the Clean ITC would be recovered if eligible property is subject to a change in use or sold within a certain period of time.

As of this date, there are no specific details regarding the proposed Clean ITC and has not been legislated. Based on assumptions on the capital that could be eligible for the ITC, if the Company was able to utilize the 30% Clean ITC, the Company estimates that the after-tax NPV for the Project at a 5% discount rate would improve from $143 million to $336 million and the after-tax IRR would improve from 5.8% to 7.2%.

The initial capital expenditure contemplated in the PFS, to be incurred over the three-year pre-production period of the Project, amounts to approximately $1.7 billion , with the sustaining capital over the remainder of LOM amounts to approximately $0.6 billion . The LOM capital expenditure is summarized as follows:

Capital ($Million's)

Operating Costs

The LOM operating costs are summarized as follows:

The PFS also identified a number of potential optimizations to the Project. These include:

• Working with energy providers and Yukon government and other stakeholders on an energy strategy to reduce the costs for the project;
• Additional metallurgical testwork to improve overall recoveries of all payable metals where a 1% recovery improvement represents approximately an after-tax $111 M improvement to the NPV at a 5% discount rate; and
• Continue drilling on the Arch target to define the potential resource which could provide the opportunity for an early project higher grade feed that may improve overall financial results.
