Castle Minerals Limited (ASX: CDT) - Five-Year Financial Review FY2021-FY2025

Five June-year annual reports, with figures in Australian dollars unless each table states otherwise. The report separates statutory profit and cash flow from capital movements and Mineral Resource snapshots.

Financial years ended 30 June 2021, 2022, 2023, 2024 and 2025 · Editorial review: 2026-09-24 · MII Research

Reading the tables: 0 (nil) is a supported zero. Other text distinguishes an amount included in another line, a non-applicable item, a separately unavailable component and an unresolved value. These are not interchangeable. Period-specific detail is labelled; complete year-by-year detail remains available.

FY2025 attributable loss

A$3.67m

Statutory continuing operations.

FY2025 operating cash flow

(A$2.83m)

Net outflow, not earnings.

Cash at 30 June 2025

A$2.50m

Consolidated cash equivalents.

FY2025 exploration expense

A$2.57m

Charged to profit or loss.

Five years in context

Castle is an exploration-stage group with losses and operating cash outflows in every year shown. Its FY2023 spending peak coincided with the maiden Kambale graphite resource; by FY2025 cash had rebuilt after further share issues. Directors continued to disclose a material going-concern uncertainty.

Comparisons require care: FY2023 term deposits sit outside cash equivalents, FY2025 EPS reflects a 1-for-30 capital consolidation, and the FY2025 segment reconciliation contains small differences from the primary financial statements.

Events behind the numbers

FY2021

Exploration licences expanded

Castle added five Earaheedy Basin licences during the year and disclosed a material going-concern uncertainty.

FY2022

Equity raised

The group raised A$5.53m through ordinary shares for Western Australian and Ghana exploration.

FY2023

Kambale maiden resource

The maiden Kambale graphite estimate was reported as 15.6 Mt at 9.0% TGC; exploration expense rose substantially.

FY2024

Wanganui and Polelle option

A November 2023 option gave Great Boulder a path to acquire 75% in the projects, while Castle retained a royalty.

FY2025

Capital consolidated; Beasley Creek sold

Shareholders approved a 1-for-30 consolidation in April 2025. Castle sold its 80% Beasley Creek interest in June, retaining a 1.6% royalty.

FINANCIAL REVIEW / 01

Statutory result and per-share basis

Castle remained loss-making in each year. Exploration expense was the largest separately stated charge; FY2023 was the highest-loss year in this window. The 2025 statement continues to present the activity as continuing operations.

The FY2025 EPS note's FY2024 comparative prints (5.1) cents and 39,765,767 weighted-average shares alongside A$2,881,373 attributable loss. The printed loss and share count imply about 7.25 cents, leaving an unresolved internal source conflict. The FY2024 annual report originally printed (0.2) cents on 1,192,973,023 shares; this report preserves each annual statement's figures.

Continuing operations; source year amounts in AUD. From FY2024 the primary statement has an 'Other income' line, with no separate revenue line. Earlier revenue and other income retain their source labels.

FY2025 Directors' five-year summary prints other income of A$21,353, while the primary statement prints A$21,352; the primary statement governs this table. The discrepancy is retained for review.

For comparison, the combined incoming-items row adds separately reported Revenue and Other income in FY2021–FY2023 and uses the single statutory Other income line in FY2024–FY2025. The component rows remain visible; the combined row is not additive to them and does not assign a separate revenue figure in FY2024–FY2025.

Basis and presentation notes (11)

Revenue / FY2024 — Included in combined line: The FY2024 consolidated P&L begins with a single Other income line (R002484); it does not attribute a separate revenue component. The combined incoming-items row uses that reported amount once, without asserting a revenue value.
Revenue / FY2025 — Included in combined line: The FY2025 consolidated P&L begins with a single Other income line (R002941); it does not attribute a separate revenue component. The combined incoming-items row uses that reported amount once, without asserting a revenue value.
Other income / FY2023 — 0 (nil): FY2023 statutory Other income line is explicitly nil.
Finance costs / FY2021 — 0 (nil): FY2021 comparative statutory finance-cost line is explicitly nil.
Finance costs / FY2024 — 0 (nil): FY2024 statutory finance-cost line is explicitly nil.

FY2021–FY2024 figures are each year's primary statement. FY2025 reflects the 1-for-30 share consolidation. Its FY2024 comparative prints (5.1) cents and 39,765,767 shares against A$2,881,373 attributable loss; those comparative figures do not reconcile arithmetically (about 7.25 cents using the printed loss and share count). The printed figures are preserved; no EPS trend is charted.

FINANCIAL REVIEW / 03

Cash outflows, investing and funding

Operating activities consumed cash throughout the period. FY2023 also included a A$2m placement into term deposits; that movement reversed in FY2024 investing cash flows. Equity issues funded the exploration program.

FY2021 sale-of-PPE proceeds are nil under R001019; earlier R000385 belongs to FY2020 comparative PPE payments. FY2022 term-deposit payments are explicitly nil in FY2023 comparative R001751. One-off financing and refund rows with no separate line remain marked not separately presented.

FINANCIAL REVIEW / 04

Shareholder returns and capital structure

No dividends were paid, declared or recommended in the five years. The April 2025 approval of a 1-for-30 share consolidation changes the denominator of the FY2025 EPS calculation and prevents an unqualified per-share trend.

FINANCIAL REVIEW / 05

Exploration footprint and project evidence

The Ghana segment accounts for most exploration expense in the FY2025 segment note. Castle's Kambale graphite Mineral Resource figures are reported as snapshots; they do not represent production or cash-generating operations.

Exploration segments: geographic expenses and other income

AUD

Metric	FY2024	FY2025
Segment other income: Australia	50,000	6,003
Segment other income: Ghana	0 (nil)	8,083
Segment other income: total	50,000	14,086
Tenement acquisition and exploration: Australia	(443,770)	(140,450)
Tenement acquisition and exploration: Ghana	(1,547,939)	(2,428,955)
Segment loss before tax: total	(2,112,170)	(2,807,023)

FY2024 amounts are the comparative column of the FY2025 segment note. This is a latest-basis two-year comparison, not a reconstructed five-year segment trend.

The FY2025 segment-note reconciliation prints A$3,670,404 loss before tax, A$200 less loss than the A$3,670,604 primary statement; the primary statement is the financial anchor. The FY2024 geographic exploration components sum A$3 above the primary statement expense. No balancing item has been invented.

Basis and presentation notes (1)

Segment other income: Ghana / FY2024 — 0 (nil): The FY2025 segment note's FY2024 comparative column explicitly shows a dash for Ghana segment other income; this is the matching geography, metric and period.

Kambale graphite Mineral Resource disclosed in annual reports

Metric units in row labels

Metric	FY2023 report	FY2024 report	FY2025 report
Total graphite Mineral Resourcekt	15,611	22,438	22,428
Contained total graphitic carbonkt	1,405	1,939	1,939
Total graphitic carbon grade%	9.0%	8.6%	8.6%

The selected annual tables identify these as Mineral Resource snapshots at 30 June in each year, not annual production.

FY2024 prints a 22,438 kt total although its shown Indicated and Inferred tonnes add to 22,428 kt; FY2025 prints 22,428 kt. Each printed total is retained. The selected tables show footnote markers but not their footnote text.

Reading the figures

Amounts in parentheses are negative; Nil is used only for an explicit source dash or statement. Not separately presented does not mean zero or issuer non-disclosure.
FY2025 EPS uses a post-consolidation denominator; earlier annual-report EPS figures are not restated in this report.
The FY2025 segment note's loss-before-tax reconciliation is A$200 different from the primary statement, and its FY2024 exploration component sum differs by A$3. The primary statements govern statutory totals.
The Kambale resource row is a disclosed estimate, not annual production. The FY2024 printed total exceeds the sum of its displayed components by 10 kt; linked footnote text was unavailable in the selected resource tables.
