Notice of Change of Auditor regulatory

"NOTICE OF CHANGE OF AUDITOR Goldgroup Mining Inc. (the “Company”) hereby gives notice"

A notice of change of auditor is a formal announcement that a company is switching the independent firm that reviews and signs off on its financial reports. Investors care because the auditor is the third-party check on a company’s numbers; changing that checker can be like hiring a new doctor or inspector — it can indicate routine rotation, a desire for a fresh view, or potential disagreements about past accounting, and it can affect confidence in the reliability and continuity of financial information.

National Instrument 51-102 regulatory

"hereby gives notice, pursuant to National Instrument 51-102 – Continuous Disclosure Obligations"

National Instrument 51-102 is a Canadian securities rule that requires public companies to regularly publish clear, standardized information about their finances and significant developments, such as quarterly and annual reports, management discussion and analysis, and notices of material changes. For investors it acts like a rule forcing businesses to keep their financial “windows” clear and up to date, making it easier to compare companies, spot risks, and make informed decisions.

Continuous Disclosure Obligations regulatory

"pursuant to National Instrument 51-102 – Continuous Disclosure Obligations"

A legal duty for publicly traded companies to quickly share any material information about their business, finances, operations, or risks with the market so all investors have the same facts at the same time. It matters because timely, equal access to key news helps prices reflect true value, reduces the chance of sudden surprises, and protects investors from unfair advantage—like keeping a public scoreboard updated so everyone sees the current score.
