Global Atomic to break ground at $208m Dasa uranium project in January November 15, 2021 | 10:21
Global Atomic (TSX: GLO) has completed the feasibility study for the first phase of its Dasa uranium project in the Tim Mersoi Basin of Niger. The company says the study confirms that the project is economic even at a price of $35 per lb. uranium oxide, thanks to an estimated all-in sustaining cost of $21.93 per lb.
The Global Atomic board has given the okay to proceed with the project.
Global Atomic plans to break ground at Dasa in January 2022 and begin underground development in April. The processing plant is to be commissioned by the end of 2024. The project is already fully permitted.
With initial capital costs pegged at $208 million, the Dasa project has an after-tax net present value (using an 8% discount rate) of $157 million and an internal rate of return of 22.7%. the project will pay for itself over the first five years of operation. Over a 12-year mine life, 45.4 million lb. of uranium oxide (U3O8) will be recovered.
At a mining rate of 1,000 t/d and an ore head grade of 5.18% U3O8, annual average production is forecast at 3.8 million lb. U3O8.
The probable reserve is 4.25 million tonnes grading 5.18% U3O8 for 48.6 million lb. of U3O8.
Phase one mining will take place in the Flank zone, which represents only 20% of the known Dasa mineralization. Phase two will also recover underground ore, and after several decades, phase three will consider an open pit to mine the lower grade surface mineralization.

Uranium & Nuclear Power Play a Critical Role in the U.S.
BY JOHN CIAMPAGLIA, CFA, CEO SPROTT ASSET MANAGEMENT | MONDAY, NOVEMBER 15, 2021
Nuclear power meets approximately 20% of U.S. electricity demand. However, what is more notable, is that nuclear power generates more than 50% of the carbon-free electricity in the U.S.1 As the country and the world take steps to tackle greenhouse gas emissions, we believe that nuclear power will continue to be a critical part of the solution.
Uranium is Key to Nuclear Power
As background, nuclear power stations in the U.S. and worldwide rely on the fission of uranium atoms to create heat. Nuclear reactors use uranium fuel that is assembled so that a controlled fission chain reaction can be achieved. The heat created by splitting the uranium atoms, typically the type known as U-235, is then used to make steam which spins a turbine to drive a generator, producing electricity.
“Nuclear power helps the U.S. avoid 470 million metric tons of carbon in the atmosphere each year, the equivalent of an additional 100 million cars on the road.”
Most U.S. reactors use enriched uranium as their fuel source. Natural uranium in the form of U3O8 concentrate, also known as yellowcake, is refined and then enriched to boost the level of the U-235 isotope from 0.71% up to 3-5%. The enriched uranium is converted into powder, which is then pressed into small ceramic fuel pellets stacked together into sealed metal tubes called fuel rods. Control rods, usually made of boron, help control the fission process, along with water.
To understand the dynamics of nuclear power in the American utility market, it helps to review the history of nuclear energy in the U.S. and the footprint of nuclear plants in operation today.
According to the United States Nuclear Regulatory Commission (NRC),2 the U.S. currently has 94 nuclear reactors operating at 56 power plants in 28 states. Most of the plants are east of the Mississippi River, and many are located on coastlines to take advantage of the cooling power of natural bodies of water.

The first light bulb powered by nuclear energy lit up in 1948, thanks to a prototype nuclear reactor in Tennessee. By 1951, a bigger experimental nuclear reactor, located in the desert in Idaho, successfully created more substantial batches of electricity. By 1955, the first operational plant was generating enough electricity to power the small town of Arco, Idaho.
Following these successes, the 1960s saw a push to commission additional nuclear reactors. Utility companies viewed nuclear power as an economical option, in addition to being a cleaner form of energy. Rising commodity prices in the early 1970s supported the popularity of nuclear. The oil embargo of 1973 was a catalyst to sign even more reactor deals as Americans lived through oil shortages, high energy prices and the other costs of foreign energy dependence. 1973 marked the peak of new reactor orders, with 41 orders placed that year. 3

Three Mile Island was a pivotal point in the popularity of nuclear energy. The partial meltdown of a nuclear reactor in 1979 near Harrisburg, Pennsylvania, was the first major global nuclear accident, although it resulted in no deaths or injuries to plant workers or members of the nearby community.4 Dozens of orders for nuclear reactors were canceled following the accident. However, because reactors are built on a long timeline, quite a few were already under construction and came online in the 1980s.
Though popularity dove after the 1979 episode, the incident arose from a design flaw and operator error. Only small changes were made to reactor design in the years that followed, though more substantial changes were made in operator protocols and regulatory oversight. Though public opinion of nuclear declined, safety and reactor efficiency (in terms of the percentage of time that reactors were operating) both climbed substantially.
Even our greenest energy sources have negative impacts on humans. These impacts fall into three broad categories: air pollution, accidents and greenhouse gas emissions. Overall, nuclear power is responsible for the lowest mortality rate per terawatt hour (TWh) of energy produced, as shown in Figure 4. Nuclear regulation is ever-evolving and among the most stringent among the energy industries, given its visibility and the weight of public and political opinion.

Why Nuclear Plants Are Mostly in the East
Looking at the map of nuclear plants across the U.S., state-by-state factors come into play regarding which states make nuclear power and which do not.
For instance, there are no nuclear plants in western states with access to significant hydroelectric power from dams or other structures around flowing water, including Oregon, Idaho (which shut down early nuclear generators in 1994), Montana and South Dakota. On the other hand, coal-mining states and their immediate neighbors are less likely to have nuclear plants, including Wyoming, West Virginia, Kentucky, Colorado, Utah and Indiana.
Biden’s View on Nuclear
The Biden Administration has put environmental concerns at the top of their priority list since the outset. In the energy sector, they have announced a goal to achieve net-zero carbon electricity by 2035, according to Biden’s climate advisor, Gina McCarthy.5
The growth of renewable energy sources, including hydro, wind and solar, contributes substantially toward the net-zero carbon electricity goal. But those sources are not projected to grow fast enough to meet the demand for electricity, plus they generate variable electricity loads based on environmental conditions. Nuclear power, on the other hand, is known for being the baseload provider. Utilities run nuclear reactors around the clock, in part to maximize their economic value – nuclear plants have high capital costs to depreciate but extremely low fuel costs.
McCarthy told the Washington Post in May 2021: “…we do have nuclear facilities that provide significant baseload capacity…we do know that there are many regions in which at least the states themselves feel like the support for those facilities needs to continue while we build an infrastructure of [renewables].”
Support for the existing infrastructure means support for maintenance and upgrades to reactors. Since the wave of nuclear plant building in the 1970s and 1980s, very few new reactors have come online. Most nuclear reactors in the domestic infrastructure are near the end of their 40-year operating license. Fortunately, “uprating” reactors – small improvements to implement technological advances – can extend the productive life of reactors and even bump up their efficiency.
Biden’s team has also expressed support for development efforts on SMRs, small modular reactors. SMR design could potentially cut down on both time and cost to build new reactors going forward.
A Valuable Source of Clean Energy
Without nuclear power, carbon emissions from electricity production in the U.S. would have been substantially higher over the last 40 years. To put this in perspective, if the current electricity from nuclear came from coal or oil, it would generate an additional 470 million metric tons of carbon in the atmosphere each year6 – the equivalent of an additional 100 million cars on the road.
With the drastic improvements in safety and the critically important role of baseload stability, nuclear power offers important benefits to the push for net-zero carbon energy. These characteristics remain important as the country moves toward a higher mix of renewables in its electric grid. Ranked fifteen in the world among countries most reliant on nuclear energy, the U.S. has the potential to expand its nuclear power reliance greatly.
The U.S. Department of Energy estimates that demand for electricity will rise 24% by 2035. The U.S. will need hundreds of new power plants to meet this demand, and these plants will need to take advantage of diverse fuel sources. It is estimated that to maintain nuclear’s 20% share of U.S. electricity generation, 20-25 new nuclear power plants will need to be operational by 2035.

: Azincourt Energy Updates Upcoming Drill Program
VANCOUVER, British Columbia, Nov. 17, 2021 (GLOBE NEWSWIRE) -- AZINCOURT ENERGY CORP. (“Azincourt” or the “Company”) (TSX.V: AAZ, OTCQB: AZURF), is pleased to provide an update on preparations for the winter 2022 exploration program at the East Preston uranium project, located in the western Athabasca Basin, Saskatchewan, Canada.
The primary target area for the 2022 program continues to be the conductive corridors from the A-Zone through to the G-Zone (A-G Trend) and the K-Zone through to the Q-Zone (K-Q Trend) (Figures 1 and 2). The selection of these trends is based on a compilation of results from the 2018 through 2020 ground-based EM and gravity surveys, property wide VTEM and magnetic surveys, and the 2019 through 2021 drill programs, the 2020 HLEM survey indicates multiple prospective conductors and structural complexity along these corridors.
The 2019-2021 drilling programs on the A-G Trend confirmed that geophysical conductors comprise structurally disrupted zones that are host to accumulations of graphite, sulphides and carbonates. Anomalous radioactivity has been demonstrated to exist within these structurally disrupted conductor zones. The 2022 drilling program will target similar structurally disrupted zones prioritized on the presence and strength of corresponding electromagnetic, magnetic and gravity geophysical anomalies.
Winter 2022 Diamond Drilling Program
TerraLogic Exploration Inc. has been contracted to facilitate and execute a planned diamond drilling program, which will consist of a minimum of 6,000m of drilling in 30-35 drill holes. Drilling will focus on the A-G and K-Q trends, commencing in the G Zone where the 2021 drill program ended. The program will continue to test the G zone to the south and then move to test the K-Q trend. The program may be modified as results warrant.
Preparations are well underway and contractors for drilling, camp services and roadwork have been selected. Opening of the 60 km winter road to access the property and campsite is expected to commence by the end of November, with camp construction in late December and into early January. Drilling is anticipated to commence in early January utilizing two diamond drill rigs to complete the program.
