How to verify company claims in EDGAR without getting fooled by the exhibit type

Before you trust a company claim, lock three basics first: filing date, form type, and source type. In EDGAR, those metadata decide how you read the text, not the other way around.

The Pretium EX-99.1 shows why date discipline matters: the filing date is not the same thing as the report’s effective date, so a claim can be technically old even when the filing is new[[cite:1]][[cite:2]][[cite:3]].

That same EX-99.1 can confirm the exhibit label, filename, report title, named authors, project, and that it was prepared to comply with S-K 229.1300[[cite:4]][[cite:5]]. But it cannot by itself prove legal title, completed transactions, reserves, or that projections will come true[[cite:6]].

For technical-report material, the Lithium Argentina excerpt can confirm the report’s own subject matter and that it is framed as a scoping study prepared for S-K 229.1300 compliance[[cite:7]][[cite:8]]. It cannot confirm filing date, form type, or EX-10 or XBRL hooks from the excerpt alone[[cite:9]][[cite:10]].

Inline XBRL is different: the viewer lets you inspect tagged facts with highlight borders, the Fact Review Window, search, and filtering[[cite:11]][[cite:12]][[cite:13]]. It can confirm what is tagged, but not an untagged narrative claim on its own[[cite:14]][[cite:15]].
