Uranium Overview

How It Works

Uranium is a naturally-occurring element in the Earth's crust. Traces of it occur almost everywhere, although mining takes place in locations where it is naturally concentrated. To make nuclear fuel from the uranium ore requires first for the uranium to be extracted from the rock in which it is found, then enriched in the uranium-235 isotope, before being made into pellets that are loaded into assemblies of nuclear fuel rods. These fuel rods are then grouped together to form fuel assemblies, which make up the core of a reactor. In the reactor core the uranium-235 isotope fissions or splits, producing a lot of heat in a continuous process called a chain reaction. At a nuclear power plant, the heat from fission is used to produce steam, which spins a turbine to generate electricity. (Source: World Nuclear Association)

Uranium: Global Energy Source

Nuclear power and hydropower form the backbone of low-carbon electricity generation. Together, they provide three-quarters of global low-carbon generation. Over the past 50 years, the use of nuclear power has reduced CO2 emissions by over 60 gigatonnes – nearly two years’ worth of global energy-related emissions. Global demand for electricity is set to grow 50% by 2040 and nuclear energy will play an integral role in meeting this demand. The WNA reports that there are 435 nuclear reactors operable in over 32 countries. These reactors can generate approx. 400 gigawatts of electricity and supply approx. 10% of the world's electrical requirements. There are 60 nuclear reactors under construction in 15 countries with the principal drivers of this expansion being China (21 reactors under construction), the Middle East, Russia and India. Furthermore, the WNA reports that there are over 400 reactors that are either ordered, planned or proposed.

According to UxC, global nuclear power capacities are projected to increase from 379.4 gigawatts in 2015 to over 483 gigawatts by 2030. Uncovered demand rises rapidly over the coming years increasing to 20% of demand over 2021, 50% of demand in 2025, and UxC also estimates that annual uranium demand could grow nearly 65% to more than 300 million pounds U3O8 by 2030 from just under 200 million pounds U3O8. The primary mine supply for 2018 was approx. 138 million pounds U3O8.

Uranium Market Commentary and Update:

The underlying supply-demand fundamentals for uranium are the strongest we have seen in a long time and dictate that a uranium price increase is needed. In the last few years we’ve seen a major supply side response play out with low uranium prices forcing production/supply curtailment which has been exacerbated by the pandemic. At one point, almost 50% of primary mine supply was offline as the virus caused several operations to shut down temporarily. The uranium mining industry globally is reliant on supply highly concentrated both geologically and geographically and this makes the risks to the supply side far greater than the risks to the demand side. This has been seen recently with Russia's invasion of Ukraine, causing a crushing energy crises as Russia cut natural gas supplies, pushing some countries to delay plans to phase out nuclear energy and cut dependence on Russian nuclear fuels.

Before 2021, the world’s largest producers of uranium, Kazatomprom (the world’s largest producer headquartered in Kazakhstan) and Cameco (the second largest producer headquartered in Canada), scaled back operations and became buyers directly in the spot uranium market to make up for decreased production. At a price around $40-$50 per pound of U3O8, it is more profitable for them to buy in the spot market and sell into their higher priced contracts with nuclear utilities. However, Cameco recently announced the restart of its McArthur River and Key Lake operations earlier this year, highlighting increased interest from contract buyers. Furthermore, much like we have seen leading up to previous uranium bull markets, there has been significant underinvestment in new mining projects which will further strain an already reduced supply side for years to come.

In 2023 there will be approximately 146 million pounds of primary mine supply in the backdrop of over 194 million pounds of uranium demand with a cumulative gap estimated to be over 300 million pounds by 2030. This supply deficit will surely help drive higher uranium prices going forward. 

Shifting over to the demand side, the story has been improving, now exceeding pre-Fukushima levels, and has been outstripping primary supply over the past couple years. Finite inventories and other secondary supplies are being depleted to make up the difference. Furthermore, well over 50% of all utility uranium contracts require renewal before expiry in 2027. Utilities typically have a requirement to renew contracts 18-24 months before existing contracts expire, and therefore several utilities have recently come to the market with new RFP’s but uranium producers are unwilling to lock in long term contracts pricing their material close to the current uranium price. 

Nuclear reactor demand for uranium is sticky and has been somewhat insulated to the COVID-19 pandemic versus other sources of electricity generation. It is still the only source of reliable, baseload, emissions-free electricity we have.  The Reference Scenario of the 2021 edition of the World Nuclear Association's Nuclear Fuel Report shows a 27% increase in uranium demand over 2021-30 (with many new cores being required, and electricity demand expected to have fully recovered following the pandemic). Demand thereafter will depend on new plants being built and the rate at which older plants are retired – the Reference Scenario of the 2021 Nuclear Fuel Report has a 38% increase in uranium demand for the decade 2031-2040.  

In addition to the current 435 operating reactors globally, demand is expected to increase on the back of new reactor construction in which there are currently 60 new nuclear reactors under construction. Demand is set to continue to grow, as governments aim to reduce emissions and focus on decarbonization and electrification. In recent news, the EU Taxonomy included nuclear as an environmentally sustainable investment, and we have seen leaders understanding that nuclear energy needs to play a larger role in order to move away from dependency on Russian oil and gas. In addition, there have been new financial entities like Yellow Cake and Sprott Physical Uranium Trust purchasing millions of lbs of uranium recently, which has put upward pressure on the price. The bottom line is that nuclear energy continues to have a positive outlook as an ideal source of clean, scalable, baseload, and affordable energy source. 

Since 2003 we have experienced 8 periods where the uranium price has spiked significantly over a short period of time - the average uranium spot price increase was 58% over an average of only 6.6 months.

Uranium: Prices

Nuclear utilities purchase uranium primarily through long-term contracts. These contracts usually provide for deliveries to begin two to four years after they are signed and provide for delivery from four to ten years thereafter. In awarding medium and long-term contracts, electric utilities consider the producer's uranium reserves, record of performance and production cost profile, in addition to the commercial terms offered. Prices are established by a number of methods, including base prices adjusted by inflation indices, reference prices (generally spot price indicators, but also long-term reference prices) and annual price negotiations. Contracts may also contain annual volume flexibility, floor prices, ceiling prices and other negotiated provisions. Under these contracts, the actual price mechanisms are usually confidential.

The long-term demand that actually enters the market is affected in a large part by utilities' uncovered requirements. Uncovered demand is projected by UxC to increase significantly over the period of 2018 to 2030. In order to address the rising portion of demand that is uncovered, utilities will have to return to the market and enter into long-term contracts. Owners and operators of U.S. civilian nuclear power reactors (civilian owner/operators, or COOs) purchased a total of 48 million pounds U3O8 equivalent (U3O8e) of deliveries from U.S. suppliers and foreign suppliers during 2019, at a weighted-average price of $35.59 per pound U3O8e. The 2019 total of 48 million pounds U3O8e was 20% higher than the 2018 total of 40 million pounds U3O8e. The 2019 weighted-average price of $35.59 per pound U3O8e was 8% lower than the 2018 weighted-average price of $38.81 per pound U3O8e (source: eia.gov). This illustrates the increased demand we are seeing that will ultimately result in a higher spot price.

Uranium: Exploration in the Athabasca Basin, Northern Saskatchewan

The uranium (U3O8) deposits of Saskatchewan, Canada are the richest in the world. The Athabasca Basin is an ancient sedimentary basin which hosts the world's most significant uranium mines and produces almost 20% of the current world uranium production in a safe and favourable jurisdiction. Athabasca uranium deposits also have grades substantially higher than the world average grade of under 0.2% U3O8.

Why The Athabasca Basin?

The Athabasca Basin is home to the world’s largest and highest grade uranium mining and milling operations – including the McArthur River and Cigar Lake uranium mines, as well as the Key Lake and McClean Lake uranium mills. Saskatchewan is also consistently ranked as a top mining jurisdiction to work in globally by the Fraser Institute. Skyharbour holds an extensive portfolio of uranium and thorium exploration projects in the Basin and is well positioned to benefit from improving uranium market fundamentals with fifteen projects, ten of which are drill-ready. Skyharbour has acquired from Denison Mines, a large strategic shareholder of the Company, a 100% interest in the Moore Uranium Project which is located 15 kilometres east of Denison's Wheeler River project and 39 kilometres south of Cameco's McArthur River uranium mine.
