Effect
The improvement affects the same mining sources as Placer Mines. It is a rate increase, not a Coin shipment, and it does not improve income from Estates, Banks or other civilization-specific sources.
Research condition
Available in the Commerce Age at Market (Europeans and Federal Americans) , Livestock Market (Africans); requires Placer Mines. Cost: 200 food, 200 wood. Civilization access varies by roster.
Research decision
Complete the upgrade when mining remains a substantial part of the economy and the relevant deposits will last through a long gathering window. Reassess if most Coin has shifted to another source.
Mine and Mountain Monastery gathering
Amalgamation is a Commerce Age technology for Africans, Europeans and Federal Americans. It requires Placer Mines, costs 200 Food and 200 Wood and takes 30 seconds. It increases Villager gathering from Mines and Mountain Monasteries by 20%. African players research it at the Livestock Market; Europeans and Federal Americans use the Market.
A broad but source-limited bonus
The upgrade affects Coin gathering from the named sources, not every economic task. It is useful when workers will remain at Mines or a Mountain Monastery for enough time to recover the cost. Since Placer Mines is required, include the prerequisite in the timing and avoid the chain if map access to those sources is poor.
