Metalwork
Metalwork is the skill having to do with making metal objects.

Prospecting and Mining
The metal is obtained from various ores that have bits of that metal within them. Unlike RS2, there are no longer 1x1 tiles of ore-rock jutting out of the ground. Instead, players can mine in any wilderness place (ie. forests, deserts, caves, beaches, prairie, snowdrifts, even in shallow rivers, which are walk-able). Players can prospect any such tile they're standing on and metal in the 9 tiles in the 3x3 matrix around the player's tile are prospected. Then they can mine, and after a few seconds' digging those 9x9 tiles become "upheaved" with chunks of darker dirt flung everywhere, like real prospecting. The metal they obtain differs depending on where they are mining. Each of those 9x9 tiles have various ores in them that change roughly every hour, effectively "jumping around". Certain regions of the map have slightly better concentrations of the more desirable ores. Places that have been mined become exhausted of the metal they contained and it takes an hour for them to replenish. Replenishing isn't noticeable as the "upheaved ground" gradually returns to normal after just 10 minutes of no activity.

Bars
It is now much harder to create metal items. Bars are much more valuable than they used to be. A bar of metal works a bit like a progress bar; its mass grows as you smelt more ore and add it to the bar in its specified ratio (so you can't imbalance the bar by smelting non-ratio amounts onto it). As a unit of storage, it can also be partially used up. For example, a dagger uses less than one bar, so you can take a nearly complete bar to make it with, and you'll have some portion of the bar left over. Several partial bars can be smelted into fewer more complete ones, optionally giving you complete bars, and vice versa. Bars all take up a lot of ore to finish. Players will often have to make plenty of trips to complete one.

Metals
You're rarely ever going to get a gold or platinum bar. A completed gold bar can also be converted for exactly 300,000 gp (those are some awfully small gold pieces!).

Smithing
Smithing is done on an anvil by any player with a hammer. Things take considerably longer to smith; while smithing, there is a progress bar that gradually goes across the bottom of the screen. Metal items are worth much more than they have before.

Trimming
You can trim weaponry and armour with your choice of either gold, red, or silver. This requires those particular bars, eg. silver trim requires part of a silver bar. Trimming is rather expensive, but it certainly adds decorative features to otherwise ordinary-looking items.
