Benjamin Hill Mining Corp. recently announced it has completed three drilling holes at its Sonora property, located within the Caborca gold belt, as a part of its inaugural drill program.
The company’s main goal for commencing the program is to “intercept and delimit mineralized structures, to better define alteration footprints and to explore for the source of mineralization.” The drilling campaign will consist of 34 exploration drill holes total over four different mineralized areas within the Sonora project, which are Sonora Copper, El Fierro, Caracahui, and La Salada.
The first two out of the three holes already drilled focused on the Sonora Copper area, which is defined as a “striking mineralized structure which outcrops over 1070 metres in length and extends to a depth of at least 200 metres.” The third hole was drilled in the Caracahui area and hit depths of 224.5 metres, and drilling has already begun at the fourth hole in the same area.
While using a field mapping program to “pursue interesting gravimetrical targets,” the company discovered additional mineralization that needs to be further investigated. The plan is to have the drill test the Crestado mineralized system, which is in the southern part of the Caracahui Area, in order to help define the additional minerals.

The company is known for operating two main projects within the The Caborca gold belt, the Sonora property and the Benjamin Hill property. The Benjamin Hill property is home to several historical mines that are still in operation, including La Herradura, San Francisco-Llano, El Chanate, Soledad Dipolos, and Noche Buena. The San Francisco mine is known to have produced over one million ounces of gold to date.
Completed Geophysical Survey
Benjamin Hill recently completed an induced polarization /resistivity survey at its Sonora property, which is used to detect geological anomalies that are under the ground. The survey took place across eight different locations, including Sonora Copper, El Fierro, Caracahui, La Quebrada, El Crestado, El Tanque, Las Antennas and La Salada.
The company used survey lines oriented from east to west to complete the survey and “perpendicularly transect known north-south mineralization trends.” These mineral trends are known to be enriched with gold, silver and copper.
The main goal of conducting this survey is to locate potential geological anomalies that indicate the subsurface vertical and lateral continuity of surface mineralization and hydrothermal alteration. The survey also provides confirmed, extrapolated drilling targets, and may provide additional mineral property information, unknown areas of mineralization, and a buried fertile pluton.
