How long is the inexperience miner permit (Green Card) issued for?

• A. 3 Years
• B. 1 Year
• C. 5 Years
• D. 2 Years

Answer: (A)

The main idea is that an inexperience miner permit, often called a Green Card, is a temporary credential that lets a new miner work on a surface mine under supervision while they complete required training and gain on‑the‑job experience. The standard duration for this permit is three years. That three-year window gives enough time to finish training milestones and prove competent in the tasks the miner is allowed to perform, without unduly delaying progression to a full credential. After three years, the miner should be upgraded or renewed based on meeting the regulatory requirements and demonstrated proficiency. The other choices don’t align with the typical regulatory timeframe, which is why three years is the correct duration.
