How does the Ore Refinery bonus work?

Ore symbols collected during gameplay fill a refinery meter. Once the meter reaches capacity (usually 15-20 ore symbols), all ore on the reels transforms into refined tantalite symbols worth 5x their original payout value for that spin.

What are the Mineral Jackpot tiers?

Quartz (smallest, triggers most often), Feldspar (mid-range), Coltan (large), and Tantalite (grand jackpot). Jackpots are triggered randomly and are not tied to bet size, though higher bets increase the probability.

Tantalite Treasure by Red Tiger Gaming delves into South Africa's rare mineral mining industry, set in a tantalite mine in the Northern Cape's Namaqualand region. The classic 5x3 grid with 20 paylines features raw ore, refined ingots, drilling equipment, and geologist symbols. The Ore Refinery bonus is the centrepiece — collected ore symbols fill a refinery meter, and when full, raw ore transforms into refined tantalite worth 5x the original value. The Drill Down feature randomly activates, drilling through reels to reveal hidden high-value symbols beneath. A Mineral Jackpot system offers four progressive tiers: Quartz, Feldspar, Coltan, and Tantalite. Medium volatility with 96.2% RTP and a 7,500x maximum win — a solid mining slot with educational mineral facts woven into the gameplay.
