Start with three distinctions.
The legal business that publishes announcements and financial reports.
The instrument being traded. Check its type and identifier; a ticker alone is not the full description.
The venue where a security is listed or quoted. One company can appear in more than one market.
Understand the TSXV, CSE and OTC markets.
The TSX Venture Exchange (TSXV) and Canadian Securities Exchange (CSE) are Canadian stock exchanges. Both include mining and mineral exploration companies. OTC Markets Group operates US over-the-counter markets with different reporting categories. A US OTC quotation is distinct from a Canadian exchange listing.

The National Stock Exchange of Australia (NSX) is separate from the ASX. An overseas company can also have securities admitted to the NSX. Confirm the legal issuer, both market codes and the type of security. An Australian CDI can represent an interest in an overseas share; it is not necessarily the same instrument in a different currency.
Use the current NSX security record and the overseas exchange or quotation record together. A proposed or conditional admission is not evidence that trading has started.
Explore NSX dual listingsBuild a small source list.
Start with the issuer’s investor website. Locate its latest financial statements, company announcements and relevant technical reports. Keep dates with your notes and check whether a later document changes the earlier position.
For Canadian issuer filings, use SEDAR+. For US filings, check the applicable SEC or OTC Markets disclosure pages. The available documents depend on the issuer’s reporting obligations.
Ask about the specific market.
Ask your broker which securities and markets it supports, which currency is used, what fees apply and how settlement works. Ask about the TSXV, CSE and US OTC markets separately. Access to one does not establish access to another.
Read the result and its limits together.
For each announcement, record what happened, the evidence, any assumptions and what has yet to be completed. Keep a plan separate from a delivered result.
