What was the impact of new silver mines in the 19 century?

The discovery of new silver mines in the 19th century, particularly in regions like the American West and parts of Latin America, significantly boosted local economies and attracted a wave of Immigration and investment. This influx of silver contributed to the global economy, increasing the money supply and facilitating trade. Additionally, it played a crucial role in the financing of infrastructure projects and the expansion of railroads. However, the rapid extraction also led to environmental degradation and social upheaval in mining communities.
