Санта-Приска
After working with his brother for a number of years, José set off to find new mineral strikes, arriving to Tlalpujahua in 1734. Here he founded a mine that was very successful. In 1738, his brother Francisco died and Borda inherited his brother's property. Deeper exploration of the original La Lajuela mine yielded an abundance of silver. It is from this strike that Borda first funded the building of the Santa Prisca Church. When this mine had nearly run out, he discovered a richer one in the Taxco called San Ignacio. With this money, he rebuilt and expanded the Santa Prisca Church. However, the San Ignacio mine produced for only nine years.
