Mining Fiesta

Mining Fiesta is an Event that occurs when Cole (Or in some cases, Foxy or Mayor Jerry) is elected as Mayor. This event occurs during the beginning of Early Summer and Early Autumn on the Calendar, equal to a total of 10 hours and 20 minutes in real-time. The event grants players 1.5x XP, double the mining drops, and allows players to collect Refined Minerals. Refined minerals are decently profitable for early-game players because they sell for roughly on the bazaar, and are not very uncommon, has a good demand there, as well as being a good way to level up their  along the way, which is an important staple early-game to get higher skills and allow one to use the higher tier Reforge Stones.

You can get Refined Mineral by mining ores in the Deep Caverns, Gold Mine, Hub, and the Dwarven Mines. Each ore (not including stone, netherrack, or end stone) has a 1/375 chance of giving you a mineral. Fortune on your pickaxe does not buff your Refined Mineral drops after Mining Fortune has been introduced. Mining Fortune does not increase your Refined Mineral Drops.

Trivia

 * The 1.5x XP actually does stack with Cole's perk "Mining XP Buff," so during the Fiesta, players can get 2.25x base XP. This is extremely useful for leveling the mining skill.
 * There's a chance that Foxy's third perk "Extra Event" will select this as the yearly additional event.
 * The first event happened in Year 90 due to the above reason.
 * During the first few hours of the event, the drop rate of refined minerals was broken and was extremely high, this glitch was fixed later on in the event
 * The event time of the Mining Fiesta was changed from the first event. Originally, the previously named National Mining Month occur during the end of Late Summer and the beginning of Early Autumn. Now, it happens at Early Summer and Early Autumn lasting 5 hours and 10 minutes each session.
 * It used to give 2x XP, totaling up to 4x  XP. However, this was nerfed after Jerry was elected mayor.
