You are looking at a schedule called Thresholds for Tier 1 and Tier 2 activities. This is part of the Crown Minerals Act 1991, which is a law in New Zealand. The schedule is about the rules for exploring and mining different types of minerals. You can see a table that lists different types of minerals, like gold, silver, and coal. The table shows the estimated costs and amounts of minerals that are allowed for exploration and mining permits. For example, if you want to explore for gold, you need to spend at least $1,250,000. If you want to mine gold, you need to pay a royalty of at least $50,000 per year. Some words in the schedule have special meanings. A metallic mineral is a type of mineral that does not include gold, silver, ironsand, or platinum group metals. Platinum group metals are a group of special metals that include iridium, osmium, palladium, platinum, rhodium, and ruthenium. This schedule is empowered by s 2B of the Crown Minerals Act 1991.
