## Definition

a situation where people suddenly make a lot of money or find something very valuable. It can also mean a large amount of something good that happens all at once.

For teachers: a situation or event that creates sudden wealth, profit, or good fortune. Originally referring to a rich vein of ore in mining, it now describes any large-scale windfall or abundance.

## Examples

- What began as a modest discovery of gold soon turned into a full-scale mining bonanza, drawing thousands of hopeful prospectors to the remote valley in search of quick riches.
