OPERATIONS UPDATE

Rubellite contracted one drilling rig during the first quarter of 2024 to drill a total of six (6.0 net) multi-lateral horizontal wells along with one (1.0 net) vertical stratigraphic evaluation well and has kept this drilling rig running continuously at Figure Lake through break up since late March. One horizontal development well was rig released on the 14-22 Pad in mid-January. Given ungulate restrictions during the winter season, drilling operations shifted to the south end of Figure Lake to drill two wells on lands acquired in the fourth quarter at a pad in Edwand at 3-17-61-17W4 (the "3-17 Pad"), applying an OBM drilling fluid system to this pool to compare to the water-based mud results from wells drilled by the previous operator. Two additional multi-lateral horizontal wells were rig released offsetting the successful step out delineation well drilled in the fourth quarter at 6-19-62-18W4 (the "6-19 Pad") and four of six additional wells have now been rig released at 5-32-63-17W4 (the "5-32 Pad") on the Buffalo Lake Métis Settlement ("BLMS"), one of which was rig released and began load oil recovery prior to the end of the first quarter. Results from the ongoing 2024 drilling program have on average performed in line with expectations⁽¹⁾.

In early January, Rubellite re-activated its horizontal multi-lateral Northern Exploration well at Dawson (5-16-81-16W5) which was rig released in late January 2023. Production performance was monitored through the winter operating season and the well was shut-in again in late March.

The contracted rig will continue to drill an additional eighteen to nineteen (18.0 - 19.0 net) wells at Figure Lake over the last nine months of 2024, with a second rig anticipated to arrive in early June to drill up to ten (10.0 net) additional development / step-out delineation multi-lateral horizontal wells at Figure Lake over the balance of the year.

Permitting is underway and equipment has been ordered to construct a sales gas plant at Figure Lake to direct solution gas to sales beginning in the first quarter of 2025. By utilizing existing pipeline infrastructure from legacy shallow gas producers in the area, the solution gas tie-in project will not only significantly reduce emissions from the Figure Lake property where natural gas is currently being incinerated on multiple pad sites, it is also economically attractive, with a forecast rate of return of >75% on the approximately $7 million capital investment, with project payout expected in 2026 based on current forward natural gas prices and anticipated carbon credits.

Rubellite also plans to continue exploration activities to pursue additional prospective land capture and de-risking during 2024.

OUTLOOK AND GUIDANCE

Rubellite's board of directors has approved exploration and development capital spending for 2024 to be approximately $70 to $75 million to drill, complete, equip and tie-in thirty four to thirty five (34.0 to 35.0 net) multi-lateral development / step-out wells in the greater Figure Lake area and includes $7 million of capital spending required for the Figure Lake gas sales plant and related pipeline tie-ins. Also included is investment in the drilling of one (0.3 net) well to initiate waterflood at Marten Hills and ongoing exploration activities. Forecast drilling activities will be funded from adjusted funds flow, with excess free funds flow applied to reduce net debt.

Production sales volumes are expected to grow 39% to 48% year-over-year to average 4,600 to 4,900 boe/d and exit the year at 5,000 to 5,200 boe/d, poised for continued growth into 2025 with strong anticipated oil production and the addition of natural gas sales volumes in the first quarter of 2025.

Capital spending, drilling activity and operational guidance for 2024 are largely unchanged as outlined in the table below:

ADVISORIES

BOE VOLUME CONVERSIONS

Barrel of oil equivalent ("boe") may be misleading, particularly if used in isolation. In accordance with NI 51-101, a conversion ratio for conventional natural gas of 6 Mcf:1 bbl has been used, which is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. In addition, utilizing a conversion on a 6 Mcf:1 bbl basis may be misleading as an indicator of value as the value ratio between conventional natural gas and heavy crude oil, based on the current prices of natural gas and crude oil, differ significantly from the energy equivalency of 6 Mcf:1 bbl.

ABBREVIATIONS

The following abbreviations used in this news release have the meanings set forth below:

INITIAL PRODUCTION RATES

Any references in this news release to initial production rates are useful in confirming the presence of hydrocarbons; however, such rates are not determinate of the rates at which such wells will continue production and decline thereafter and are not necessarily indicative of long-term performance or ultimate recovery. Readers are cautioned not to place reliance on such rates in calculating the aggregate production for the Company. Such rates are based on field estimates and may be based on limited data available at this time.

NON-GAAP AND OTHER FINANCIAL MEASURES

Throughout this news release and in other materials disclosed by the Company, Rubellite employs certain measures to analyze financial performance, financial position and cash flow. These non-GAAP and other financial measures do not have any standardized meaning prescribed under IFRS and therefore may not be comparable to similar measures presented by other entities. The non-GAAP and other financial measures should not be considered to be more meaningful than GAAP measures which are determined in accordance with IFRS, such as net income (loss), cash flow from (used in) operating activities, and cash flow from (used in) investing activities, as indicators of Rubellite's performance.

Non-GAAP Financial Measures

Capital Expenditures: Rubellite uses capital expenditures related to exploration and development to measure its capital investments compared to the Company's annual capital budgeted expenditures. Rubellite's capital budget excludes acquisition and disposition activities.

The most directly comparable GAAP measure for capital expenditures is cash flow from (used in) investing activities. A summary of the reconciliation of cash flow from (used in) investing activities to capital expenditures, is set forth below:

Net Debt and Adjusted Working Capital Deficit: Rubellite uses net debt as an alternative measure of outstanding debt. Management considers net debt as an important measure in assessing the liquidity of the Company. Net debt is used by management to assess the Company's overall debt position and borrowing capacity. Net debt or asset is not a standardized measure and therefore may not be comparable to similar measures presented by other entities.

The following table reconciles working capital and net debt as reported in the Company's statements of financial position:

Adjusted funds flow: Adjusted funds flow is calculated based on net cash flows from operating activities, excluding changes in non-cash working capital and expenditures on decommissioning obligations since the Company believes the timing of collection, payment or incurrence of these items is variable. Expenditures on decommissioning obligations may vary from period to period depending on capital programs and the maturity of Rubellite's operating areas. Expenditures on decommissioning obligations are managed through the capital budgeting process which considers available adjusted funds flow. Management uses adjusted funds flow and adjusted funds flow per boe as key measures to assess the ability of the Company to generate the funds necessary to finance capital expenditures, expenditures on decommissioning obligations and meet its financial obligations.

Adjusted funds flow is not intended to represent net cash flows from operating activities calculated in accordance with IFRS.

The following table reconciles net cash flows from operating activities, as reported in the Company's statements of cash flows, to adjusted funds flow:

Available Liquidity: Available liquidity is defined as the borrowing limit under the Company's credit facility, plus any cash and cash equivalents, less any borrowings and letters of credit issued under the credit facility. Management uses available liquidity to assess the ability of the Company to finance capital expenditures, expenditures on decommissioning obligations and to meet its financial obligations.

Non-GAAP Financial Ratios

Rubellite calculates certain non-GAAP measures per boe as the measure divided by weighted average daily production. Management believes that per boe ratios are a key industry performance measure of operational efficiency and one that provides investors with information that is also commonly presented by other crude oil and natural gas producers. Rubellite also calculates certain non-GAAP measures per share as the measure divided by outstanding common shares.

Average realized oil price after risk management contracts: are calculated as the average realized price less the realized gain or loss on risk management contracts.

Adjusted funds flow per share: adjusted funds flow per share is calculated using the weighted average number of basic and diluted shares outstanding used in calculating net income (loss) per share.

Adjusted funds flow per boe: Adjusted funds flow per boe is calculated as adjusted funds flow divided by total production sold in the period.

Supplementary Financial Measures

"Average realized oil price" is comprised of total oil revenue, as determined in accordance with IFRS, divided by the Company's total sales oil production on a per barrel basis.

"Royalties (percentage of revenue)" is comprised of royalties, as determined in accordance with IFRS, divided by oil revenue from sales oil production as determined in accordance with IFRS.

"Production & operating costs ($/boe)" is comprised of operating expense, as determined in accordance with IFRS, divided by the Company's total sales oil production.

"Transportation cost ($/boe)" is comprised of transportation cost, as determined in accordance with IFRS, divided by the Company's total sales oil production.

"General & administrative costs ($/boe)" is comprised of G&A expense, as determined in accordance with IFRS, divided by the Company's total sales oil production.

"Heavy oil wellhead differential ($/bbl)" represents the differential the Company receives for selling its heavy crude oil production relative to the Western Canadian Select reference price (Cdn$/bbl) prior to any price or risk management activities.
