Whiteout Survival Frostfire Mine

Published: 2026-11-10

Frostfire Mine in Whiteout Survival is a solo event where you collect Orichalcum from Veins, patrol-related skills and special objectives to earn milestone and ranking rewards. Choose a hunting or gathering approach, level the event skills and watch for Vein Outbursts while managing occupied Veins. Your city cannot be attacked inside the mine, but marches can fight over collection sites. Checked in November 2026.

Times and Entry

The slot list includes 02:00, 05:00, 11:00, 14:00, 16:00, 18:00, 21:00 UTC. Read the slots offered in your event window, select the one you can attend and check its registration countdown before battle day. Convert UTC to your local US time zone rather than relying on an alliance member's local clock.

Plan around the 30-minute event window, then follow the active battlefield timer once inside. Registration, matchmaking, battlefield entry, battle and settlement are separate steps. The current sign-up panel gives the entry deadline and Furnace requirement for your run, so use it when setting a reminder.

Recall all troops before entering. Choose heroes and Gear in advance as well, since those remain part of your setup inside the event. The event calendar helps compare the slot with alliance commitments, while the Furnace guide covers your city's progression before the event becomes available.

Veins and Orichalcum

The outer zone contains level-one Veins, the middle has level-two Veins and the center has level-three Veins alongside the Smelter. Defeat the Phaethon Mine Guards before gathering. Richer Veins offer higher capacity and faster collection, but an occupied Vein can also become another Chief's target.

Capacity and rate answer different questions. Capacity tells you how much metal the site holds, while rate tells you how quickly a march gathers it before event skill effects. Compare both with the time left on the battlefield. A richer location is useful only while you can keep collecting there.

Vein Outbursts provide 4,000 Orichalcum at 200 per second, giving an unbuffed empty time of 20 seconds. Guides recommend pausing patrol hunting when free marches can collect these short opportunities. Watch the event alert rather than leaving every march committed when an outburst appears.

If a defender loses control after reaching the yield condition, some Orichalcum scatters for nearby Chiefs to collect. That is a separate opportunity from gathering the original Vein. Keep track of both the occupied site and the piles after a contested fight, especially when deciding where to send the next available squad.

Skills and Hunting Routes

Frostfire XP unlocks 5 event skill levels. Each level offers a left or right branch, and the choice stays fixed for the current event. Guides recommend choosing a plan before the first selection: hunting focuses on patrols, while gathering favors Vein collection.

The XP column is the requirement for each level, not a cumulative total. Mine Patrols provide experience: the level-one patrol row gives 75 XP and the level-two row gives 150. Choose targets your heroes can handle instead of treating the larger XP number as a reason to accept every fight.

With the first right skill, a defeated Mine Patrol yields 1,500 Orichalcum. Guides favor this hunting approach when contested Veins are too difficult to hold. Stay near manageable patrol targets and use the resulting skill progression to build a repeatable collection route.

The third left skill grants 5,000 Orichalcum for occupying a Vein, with a once-per-minute cooldown. Guides recommend keeping a squad free to collect that occupation bonus rather than tying every march to a long gathering assignment. The gathering path also takes this skill, so occupation timing matters to both listed approaches.

Buffs That Apply

Normal Gathering Speed and March Speed bonuses do not apply in Frostfire Mine. Tech Research, VIP Benefits, item effects and skin bonuses can apply under the event rules. Check the actual effect you intend to use instead of assuming that every bonus visible in your city carries over to mine gathering.

Event skills have their own effects. The second right branch adds 25% March Speed inside the event, while the fourth left branch adds 15% gathering efficiency. Those are mine skill choices, distinct from the ordinary bonuses excluded above.

Heroes retain their outside-event level and Gear, and use Expedition Skills. Prepare the roster through the hero directory and Gear upgrade guide. When a fight looks unfavorable, the hunting approach gives you another task instead of repeatedly returning to the same occupied Vein.

Smelter and Final Score

The Smelter is the central late-event objective. Follow its on-screen unlock countdown, then decide if your heroes can compete there. Occupation rank contributes Orichalcum, so it can affect the same yield total used for final ranking rather than creating an unrelated score to ignore.

The occupation reward table starts at 100,000 Orichalcum for first place and reaches 20,000 for tenth. Compare the opportunity with the collection you can still secure elsewhere. A patrol or Vein plan can continue producing while the center is contested.

Milestones and Ranking Rewards

Rewards come from Orichalcum milestones and final yield ranking. The milestone examples at 100,000 and 150,000 each award 10 Charm Guide and 6 one-hour Training Speedups. Collect milestones separately from checking your final place.

Ranking payouts vary by the event offered on your server. The ranges below show the item amounts for each placement bracket; use the reward preview in your current run for its exact combination. Charm Design and Charm Guide support Chief Charm upgrades.
