These rules come from BianKO's forum post on 24-hour Auto Mining drops (March 30, 2025) and the server info list in the OASIS launch thread. The post says it plainly: there is no mining farm on the server other than Auto Mining. Prices are from the Power Up Store on BianKO's site.

Where to get an Auto Mining voucher

Auto Mining voucher sources (prices on BianKO's site)
SourcePriceWhat else you get
Power Up Store: Auto Mining Exchange Voucher 350 AB Voucher only
VIP Package 1,500 AB Switch Premium, Valkyrie Helmet and Armor Certificate, 2x Pathos Gloves, Alseids, War Tattoo, 15-day Genie, VIP Key, 5,000 Knight Cash and potions
Farm Package 1,100 AB DC Premium, Valkyrie Helmet and Armor Certificate, 2x Pathos Gloves, Dryads Voucher, Solar Tattoo Voucher, 15-day Genie, VIP Key, 1,000 Knight Cash and potions

The forum price list from April 2, 2025 calls it "Auto Mining Voucher" at the same 350 AB. The store now lists it as "Auto Mining Exchange Voucher" under the AB tab, and it isn't sold for KC. How long a voucher lasts and which NPC or menu starts Auto Mining in game aren't listed on the site.

Do you need a package just to mine

No. Auto Mining has no premium requirement, so the 350 AB voucher on its own is enough. The packages are about premium and gear: the Farm Package brings DC Premium, the VIP Package Switch Premium. DC Premium lists 100% coins and a 26% drop bonus on the site; whether that bonus applies to Auto Mining drops isn't stated.

Auto Mining drops

On March 30, 2025, BianKO posted its 24-hour Auto Mining drop list as an image on the forum. The forum is offline now, and the list isn't on BianKO's site either, including the gems and fragments drop page. So there's no item list or rate to give here.

Outside mining, the 2025 patch notes point to three farm spots: Bowl (Bowl Guard mobs drop Ruler Box and Draki Box), the 7 Sins mobs in the garden (Dragon Certificate) and Ronark Land. The April 25, 2025 patch improved drops in Ronark Land, the CZ garden and Bowl.

FAQ

Do you need premium for Auto Mining on BianKO?
No. BianKO called this out in its March 30, 2025 post; the voucher is all you need.
Does BianKO have a Golden Mattock or fishing?
Neither, and no regular Mattock either. Mining only works through Auto Mining.
How much is the Auto Mining voucher?
350 AB in the Power Up Store. The same voucher also comes in the 1,100 AB Farm Package and the 1,500 AB VIP Package.
Does mining keep going after you log out on BianKO?
The OASIS server info says "Offline Mining: no". Logging out stops it.
