The real case in El Callao gold mine in Venezuela is that this wall is inclined in 15o with respect to the vertical. In the present paper a theoretical treatment is presented considering this inclination. The isotherm time-evolution resulting from the intrusion of a hot dike in a cold rock is analysed considering the general case of nonvertical walls. This is applied to the theoretical prediction of the gold veins location due to isothermal evolution. As in previous treatments earth surface effects are considered and the gold veins are determined by the envelope of the isotherms. The locations of the gold veins in the Callao mines of Venezuela are now well predicted. The new treatment is now more elaborated and complex that in the case of vertical walls, performed in previous papers, but it is more adequated to the real cases as the one in El Callao, where the wall is not vertical.
