About Stockle

Last updated 31 October 2026

Stockle explains oil, gas and mining companies from their own disclosures: their filings with the US Securities and Exchange Commission (EDGAR) and their Australian Securities Exchange announcements. It covers 1,908 companies and has explained 256,484 of their filings and announcements in plain English. 130 companies have an interactive valuation.

These companies tell their story one document at a time, over years and in technical language: a permit here, a placement there, a well result months later. Stockle puts the documents back together so you can see the whole story, and the numbers in it, in one place.

What you will find on each company

Announcements, explained. Each announcement in a sentence or two, with what it meant for a shareholder at the time. A capital raising shows the dilution, worked out from the company's own share counts.

The story. The events that changed the company, from its first filing to its latest, on one timeline with its shares on issue and market value. Above it is a written History of a few hundred words in chapters, built only from those events.

The calculator. For explorers that disclose reserves or resources: what the company says is in the ground, how much of it the company owns, and what that could be worth against what the market pays for the company. You choose the chance of success and development; the history of past estimates and ownership is kept, so you can test an old estimate against today's ownership.

How the work is done

Software reads every document. Figures - reserves, resources, ownership interests, wells, share counts - are extracted with the exact sentence they came from, and a figure is kept only if that sentence is found in the document. Story events are written in date order by an AI model that is given the company's history so far and the document's text, under rules that every amount, date and name must come from the document and that nothing may be added that the document does not say. Histories are written only from those checked events. Spot checks compare figures and summaries with the source documents, and errors found are corrected and the method changed.

Valuations use fixed in-ground prices (A$4 per barrel of oil, A$0.40 per thousand cubic feet of gas) rather than forecasts, so companies can be compared on the same basis. Prices are delayed closing prices.

Limits

Automated reading makes mistakes, and a company's own figures can change. Every page links back to its sources so you can check them. Stockle provides general information only: it is not financial advice and does not recommend buying or selling any security. See the terms and the privacy policy.
