Filing Released Lang Actions
Other.pdf
Regulatory Filings Classification · 1% confidence The document is a shareholder request form under NI 51-102 for receiving interim or annual financial statements and MD&A. It is not the actual report (10-K, IR, MD&A) nor an AGM presentation, earnings release, or financing update. It serves as a regulatory notice/form, so it falls under the fallback category for miscellaneous filings: Regulatory Filings (RNS).

News release - English.pdf
Capital/Financing Update Classification · 1% confidence The document is a press release announcing the completion of the first tranche of a private placement financing (issuance of units, share purchase warrants, finder’s fees) and describing the use of proceeds. This is clearly an update on the company’s capital financing activities rather than a full report, earnings release, or regulatory filing, so it fits the Capital/Financing Update category.
2025-10-28 English
Notice of the meeting and record date - English.pdf
Proxy Solicitation & Information Statement Classification · 1% confidence The document is a formal notice from the transfer agent (Computershare) to Canadian securities regulators providing details of an upcoming Annual General and Special Meeting (record dates, meeting date, proxy delivery arrangements, etc.). It is not the annual report itself, nor an earnings release or management discussion; rather it is part of the proxy solicitation process (Notice of Meeting/Information Statement). Therefore it falls under Proxy Solicitation & Information Statement (PSI).
2025-10-09 English
News release - English.pdf
Regulatory Filings Classification · 0% confidence The document is a corporate press release announcing the renewal of lithium exploration claims in Nevada. It does not report financial results (so not an IR, ER, or 10-K), nor is it an ESG, governance, dividend, M&A, or management change notice. It is not a proxy, interest rate notice, or share transaction. Since it is a general corporate announcement that does not fit a more specific category, it falls under the fallback “Regulatory Filings (RNS).”

Report of exempt distribution (45-106F1).pdf
Regulatory Filings Classification · 1% confidence The document is a Canadian securities regulator form (Form 45-106F1) reporting an exempt distribution of newly issued shares. It is neither a financial report (10-K/IR), an earnings release, nor a call transcript, and does not match any specialized filing categories (e.g., Board changes, M&A, proxy, etc.). It is a formal regulatory filing detailing a share issuance, which falls into the miscellaneous regulatory filings category.
2025-09-15 English
Material change report - English.pdf
Regulatory Filings Classification · 1% confidence The document is a National Instrument 51-102F3 “Material Change Report,” a Canadian regulatory filing announcing a significant corporate change (option agreement to acquire a lithium project). It is not an annual or interim financial report, earnings release, proxy or dividend notice, or an investor presentation. It does not fit specialized categories such as M&A takeover bids (TAR), earnings releases (ER), or share repurchases (POS). As a mandated securities filing that does not align with other specific categories, it falls into the general Regulatory Filings category (RNS).
