How to Read This Chart

This chart tracks the historical stock price of Castle Minerals over time.

Use the toggle to view price changes in absolute currency terms or as a percentage change relative to the starting date.

Total Return vs. Price Return

The "Total Return" toggle includes reinvested dividends on top of the pure price movement. This is critical because dividends can account for a significant portion of long-term returns.

Intraday Price Data

When viewing a one-day time frame, the chart displays real-time intraday price movements. This is useful for observing how Castle Minerals stock reacts to market openings, earnings releases, or breaking news throughout the trading session.

What to Look For

Look for long-term trends (sustained upward or downward movements over months and years), support and resistance levels (price zones where the stock repeatedly bounces or reverses), and volatility (how much the price fluctuates day to day). Comparing Castle Minerals's price chart to a market index like the S&P 500 can reveal whether the stock is outperforming or underperforming the broader market.

Income Statement Key Figures

Revenue and Revenue Growth

Revenue is the starting point of every income statement — it measures the total sales Castle Minerals generates from its core business. Revenue growth (expressed as year-over-year percentage change) is one of the most important indicators of business momentum. Sustained growth above 10 % annually is generally considered strong, while declining revenue is a serious warning sign that demands investigation.

Gross Margin

Gross margin = (Revenue − Cost of Goods Sold) ÷ Revenue. It reveals what percentage of each dollar of revenue Castle Minerals retains after direct production costs. High gross margins (above 50 %) are typical of asset-light businesses like software and brands, while capital-intensive industries like manufacturing often operate below 30 %. Compare Castle Minerals's gross margin to industry peers and track it over time to spot improving or deteriorating pricing power.

EBIT and EBIT Margin

EBIT measures operating profit — what remains after subtracting all operating expenses (including R&D, sales, and administrative costs) from gross profit. The EBIT margin shows this as a percentage of revenue. Because it excludes interest and taxes, EBIT allows fair comparisons between companies with different debt levels and tax jurisdictions. A rising EBIT margin indicates improving operational efficiency.

Net Income and Earnings Per Share (EPS)

Net income is the company's final profit after all expenses, interest, and taxes. Dividing net income by the number of shares outstanding gives you EPS — the single most influential metric in stock valuation. Consistent EPS growth is the primary driver of long-term stock price appreciation. Always check whether EPS growth comes from genuine profit improvement or from share buybacks reducing the share count.

Shares Outstanding

The total number of shares Castle Minerals has issued. A declining share count (through buybacks) boosts EPS and signals management confidence. A rising share count (through stock issuance) dilutes existing shareholders. Always monitor this number alongside EPS to get the full picture of per-share value creation.

Analyst Estimates

The projected figures represent consensus estimates from professional analysts. Compare these forecasts against Castle Minerals's historical growth rates to assess whether expectations are realistic. A company that consistently beats consensus estimates tends to see its stock price rewarded over time, while repeated misses erode investor confidence.

Castle Minerals stock margins

The Castle Minerals margin analysis displays the gross margin, EBIT margin, as well as the profit margin of Castle Minerals. The EBIT margin (EBIT/sales) indicates the percentage of sales that remains as operating profit. The profit margin shows the percentage of sales that remains for Castle Minerals.

Castle Minerals business model & stock analysis

Castle Minerals Ltd is an Australian mining exploration company specializing in the investigation of high-grade, potentially valuable mineral deposits. The company was founded in 2005 by former AngloGold Ashanti employee Mike Ivey and has since carried out a long list of exploration projects in Africa and Australia. Castle Minerals' business model is focused on the discovery and sustainable development of mineral resources. Therefore, the company conducts intensive exploration and drilling programs in areas that may host high-value mineral deposits. The resources can then be either processed directly or, if they meet the criteria for the development of a major mine, sold to large mining companies for further processing and exploitation. Castle Minerals operates in various areas and has already discovered a number of commodities and types of minerals in the past. The most important ones include gold, copper, iron, uranium, nickel, and lithium. The company specializes more in the exploration and discovery of mineral deposits rather than directly intervening in production or trading. Key projects by Castle Minerals include the area near the BHP Billiton Olympic Dam Mine in South Australia, which is said to have gold and copper deposits. The company has also achieved significant success in West Africa, specifically in Ghana and Western Australia. In addition, Castle Minerals has a strong presence in Mali and other countries in the region. Apart from exploration and development of resources, Castle Minerals is also involved in license allocation and exploration activities. Specifically, this involves license allocations for exploration and mining activities in Africa. The company works closely with local partners and governments to contribute to a fair and sustainable exploitation of mineral resources. Castle Minerals also has a good reputation in the industry for its unique exploration technologies and data analysis methods. The company prioritizes quality and transparency in all areas of its business model and works closely with government authorities and supervisory boards to ensure that its practices are ethical, legal, and sustainable. In terms of the products offered by Castle Minerals, the company's resources are mainly obtained from mining operations. These can be further processed in various industries, such as the electronics and automotive industry, construction industry, or energy industry. The company's portfolio mainly consists of ore minerals like gold, copper, nickel, and uranium. Overall, Castle Minerals has established a strong position as one of the leading exploration companies in Australia and Africa in recent years. With a strong focus on quality, innovation, and sustainable development, the company has built a solid portfolio of resources that it can utilize in a profitable and sustainable manner.

Castle Minerals Eulerpool Fair Value

Fair Value Estimate

What Is Fair Value?

Fair value is an estimate of what a stock is truly "worth" based on its financial fundamentals, independent of the current market price. If the calculated fair value is above the current share price, the stock may be undervalued — and vice versa. This chart shows three different fair value approaches so you can cross-check them against each other.

Earnings-Based Fair Value

Calculated by multiplying the current earnings per share (EPS) by the average historical P/E ratio over a selected multi-year period. The smoothing over several years filters out temporary spikes or dips. If this fair value exceeds the market price, it suggests the stock is cheap relative to its earning power.

Example: Fair Value (Earnings) 2022 = EPS 2022 × Average P/E 2019–2021

Revenue-Based Fair Value

Derived by multiplying revenue per share by the average historical price-to-sales ratio. This method is particularly useful for companies with volatile or temporarily depressed earnings, as revenue tends to be more stable than profits. It answers: "At what price has the market historically valued each dollar of this company's sales?"

Example: Fair Value (Revenue) 2022 = Revenue per Share 2022 × Average P/S 2019–2021

Dividend-Based Fair Value

Calculated by dividing the dividend per share by the average historical dividend yield. This approach is most relevant for mature, consistently dividend-paying companies. If the resulting fair value is higher than the current price, it implies the stock offers a better yield than its historical average.

Example: Fair Value (Dividend) 2022 = Dividend per Share 2022 ÷ Average Yield 2019–2021

How to Use This Chart

When all three fair value lines converge above the current price, it strengthens the case that the stock is undervalued. When they diverge, investigate why — it may indicate a structural shift in margins, payout policy, or growth rate. The forward estimates on the right extend the analysis using projected fundamentals, helping you assess whether the current price already reflects future growth expectations.

Annual Return

What This Chart Shows

This chart breaks down 's total annual return into two components: price return (gains or losses from stock price movement) and dividend return (income received from dividend payments). Together, they represent the total return an investor would have earned in each calendar year.

Price Return

Price return measures the percentage change in 's stock price from January 1st to December 31st of each year. Positive bars indicate the stock appreciated; negative bars show a decline. This is the component most investors focus on, but it tells only part of the story — especially for dividend-paying stocks.

Dividend Return

Dividend return represents the income generated from dividends paid during the year, expressed as a percentage of the starting stock price. While it may seem small in any single year (typically 1–4 % for established companies), dividends compound significantly over decades and have historically contributed roughly 40 % of total stock market returns.

What to Look For

Examine how many years showed positive vs. negative returns to gauge consistency. A stock with mostly positive years and small drawdowns suggests lower risk. Also compare 's annual returns to a benchmark index — consistently outperforming the market is a hallmark of a strong investment. Pay attention to the worst years: understanding downside risk is just as important as chasing upside potential.
