OVERVIEW
Royal Helium Ltd controls 354,055.726 ha (874,889 acres) of prospective helium rights across the Helium Fairway in both southwestern and southeastern Saskatchewan over 10 distinct project areas.
Royal’s helium leased and permitted lands are comprised of 10 main blocks spanning southwestern to southeastern Saskatchewan. Exploration drilling was initiated in 2021 at the Climax block in the southwest resulting in the discovery of helium in Devonian and Cambrian stratigraphic units as well as the large Climax Nazare zone that are all subject to further development wells being drilled. Drilling in the southeastern side of the province has been initiated on the Ogema block in which economic concentrations of helium were found with additional testing to be done in shallower zones. Royal has plans to fully explore and develop each of the blocks with high resolution aeromagnetic surveys (HRAM), 2D & 3D seismic acquisition, and further exploration drilling.
To date areas drilled include:
- Climax (4 wells)
- Val Marie (1 well)
- Ogema (2 wells)
- All successful with commercial helium grades tested.
Exploration plans are to drill and develop numerous anomalies of similar size to the existing Battle Creek, Wilhelm and Mankota helium pools. The exploration team uses a methodical approach that utilizes historic seismic and mapping data, geochemical & hydrodynamic mapping, HRAM, and 2D & 3D seismic to better understand the regional and local paleostructural and stratigraphic complexity of the various helium bearing formations in Saskatchewan. Multiple HRAM surveys have been flown on key land packages to begin the examination of locating deep seated basement structures with the presence of faulting and fracturing in the crystalline basement.
Saskatchewan's Commitment to Helium Production
In November 2021, the Government of the Province of Saskatchewan announced its “Helium Action Plan: From Exploration to Exports”, which outlines how the province aims to become a world leader in helium production and export over the next decade, with a goal to supply ten per cent of the global helium market share by 2030.
The Helium Action Plan which provides policy and program commitments to support and grow the entire helium value chain, is focused on exploration, production, innovation, processing and export infrastructure.

Resources
While drilling wells at Climax, Royal Helium’s geologists discovered the Nazare Zone, a 39 meter contiguous helium bearing zone at Climax-3 in the basal Deadwood Regolith which was a previously unknown helium bearing sequence. The same Regolith zone was also intersected at Climax-2 and Royal has seismically mapped the Regolith over a total area of 32 square kilometers (12.3 mi2). An independent resource estimate of Climax Nazare Zone by GLJ Ltd suggests a Best Case helium in place of 1.298 Billion cubic feet of helium in place.

Drilling & Exploration
First drilled in 2021, Royal Helium Ltd has drilled a total of 7 successful wells in 3 project areas in Saskatchewan to date, with plans to further drill and develop helium fields in Saskatchewan with the goal of bringing them to production.
In January 2021, Royal Helium commenced its maiden drill program on the Climax land block and drilled three wells to a total depth (TD) of approximately 2600 meters. Economic helium concentrations were announced in April 2021, with tests returning levels ranging from 0.33% to 0.64% helium from the Deadwood, Souris River and Duperow formations, with initial high-graded production zones being tested ranging in thickness from five meters to in excess of 30 meters.
Subsequently, further examination and interpretation of drilling at the Climax project discovered a 39-meter helium bearing zone at Climax-3 in the basal Deadwood “Regolith” which was a previously unknown helium bearing sequence. The same zone was also intersected at Climax-2 and the Company seismically mapped the new zone, renamed the Climax “Nazare” zone, over a total area of 32 square kilometers (12.3 mi2). Based on internal estimates, Royal estimates total helium in-place within the Climax Nazare zone across the prospective area to be between approximately 2.5 billion cubic feet (“Bcf”) (low-case) and 6.0 Bcf (high case). Detailed geological, rock mechanics, and engineering work has been taking place to develop the optimal horizontal wellbore design and technologies to drill into the Nazare formation to exploit large volumes of helium bearing gas. Based on the results to date from various specialized consultants, Royal has expanded the development program for the Climax Group and has applied for additional well licences on the block.
Through the collection and analyzing of newly acquired 2D & 3D seismic datasets, Royal has developed a portfolio of many conventional helium targets to exploit the large structures within the Devonian and Cambrian sections as well as a future horizontal well that will be placed into the Nazare once all of the work has been completed to de-risk the ‘resource type play’ further.
In addition to the development work at Climax, the Company intends to drill additional helium wells in its southwestern land packages in Cadillac and Val Marie that have offsetting competitor helium production in close vicinity. The southeastern land parcels, which is a vast area that historically, contains some of the highest helium shows in the province will undergo exploration drilling to be developed into an extension of largescale helium producing fairway from southwestern producing fields. Royal has completed its seismic evaluations and is undertaking the work required to license wells on multiple properties in W2 (West of 2nd Meridian) or better known as southeastern Saskatchewan.
To date, Royal Helium has drilled 7 wells in Saskatchewan – including Climax (4 wells), Val Marie (1 well drilled) and Ogema (2 wells drilled) – all of which displayed economic grades of helium concentration. Royal plans to further drill and develop our Saskatchewan projects with the goal of bringing them into production in the future.
History
Three wells were drilled into the Steveville project in 2021/2022 by Royal Helium’s subsidiary, Imperial Helium Ltd.
In August of 2022, Royal Helium received a Competent Person’s Report (“CPR“) from GLJ Ltd. of Calgary, Alberta, which provided an independent resources assessment and evaluation of the Steveville project. Best case Risked Marketable Resources of total helium in place being 145 mmcf.
In August, Royal signed the first of its offtake contracts, a direct-to-end-user and first of its kind agreement in the helium sector. In 2023, Royal completed another offtake agreement for the remainder of its helium production from Steveville.
In 2023, Royal Helium Ltd, commissioned and built the Steveville Helium Processing Facility. Designed and built in Alberta, Royal Helium’s 100% owned state-of-the-art purification facility was purpose built to recover 99.999% helium while setting the highest standards for environmental efficiencies and to produce an exceptionally low carbon footprint. The facility was completed in August of 2023, with start-up completed in November of 2023.
Drilling & Exploration
The Steveville structure was initially drilled by Standard Oil Company of B.C. in 1940, with the 100/13-22-020-12W4/00 well which had a blowout from the Beaverhill Lake Formation while drilling with no burnable (inert) gas. The Company has drilled three wells on the Steveville structure, 102/03-01-020-12W4/00, 103/10-22-020-12W4/00, and 102/12-12-020-12W4/00. Within the Beaverhill Lake Formation two zones of interest were identified by the Company, referred to as the Blowout Zone (BOZ) and Sub-Davidson Salt Zone (SDZ).
The 103/10-22-020-12W4/00 and 102/12-12-020-12W4/00 wells showcased exceptionally strong flow rates during production testing with helium concentrations ranging from 0.43 to 0.53% and has been tied into Imperial’s state of the art helium purification facility in Q4/23 that will accept 15MMCF/D raw gas.

NI 43-101 Resource
The Tres Cruces project contains a NI 43-101 Resource Estimate of 2.47 million ounces of gold at 1.65 g/t gold in the indicated category, consisting of 46.5M tonnes of oxide and sulfide material. The deposit is 100% pit-constrained and is amenable for open-pit mining. Included in this resource are 630,000 leachable ounces at 1.28 g/t gold in the indicated category, contained in 15,343,000 tonnes.
The defined leachable resource consists of oxide material and leachable sulphides. The current defined oxide leachable ounces and the immediate underlying leachable sulfide ounces demonstrate the potential for an economic standalone heap leach operation with depth expansion into the sulphide part of the deposit. If processed first, the oxide and leachable sulphide ounces would significantly off-set the capital costs of a much larger sulphide operation.
New Oroperu updated the mineral Resource Estimate to include leachable mineralization for the Tres Cruces Project in the NI 43-101 Technical Report dated February 1, 2021 which updates the prior Resource Estimate in an NI 43-101 Technical Report dated September 2012. The updated Tres Cruces resource dated as of February 1, 2021 is summarized below and can be found on the following link and is filed on SEDAR.
Indicated Mineral Resources are estimated to contain 46.5 million tonnes grading 1.65 g/t Au for a total of 2.5 million ounces of contained Au in the indicated category. Inferred mineral Resources Estimate is 19.6 million tonnes grading 0.97 g/t Au or 0.6 million contained oz Au. These estimates are reported at 0.3 g/t Au cut-off for leachable resources and 0.9% g/t Au for non-leachable sulfides which cut off grades are considered appropriate for the deposit at current long-term average metal prices.
Potential exists to increase the size of, and the confidence in, the resource through further drilling. Near-surface oxide mineralization expansion opportunities are present in areas covered by shallow post-mineral rocks. Drilling areas presently classified as Inferred Mineral Resource and in areas where holes ended in mineralization, could add or upgrade significant resource tonnage. There is deep exploration potential for additional resources including for “bonanza vein” opportunities found in feeder zones of low sulfidation systems.
No estimate has been made by the NI 43-101 authors for Ag although significant potential for value exists at current Ag prices. Indications are that silver grades are generally low and concentrated mainly in the deeper, sulfide portion of the gold deposit. Based on this updated gold resource scenario, overall silver grades would be expected to range between 1.5 and 2.5 g/t, potentially containing 2.5 to 3.5 million ounces of silver. Any silver recovered with the gold would enhance overall project economics.
