Teras Schedules Core Drilling Program at Imperial Valley Gold Mine Based on New Geologic Information


Cahuilla gold mine


IMPERIAL COUNTY – Teras Resources Inc.  announced that development drilling will commence in February 2014 at the Cahuilla gold-silver project in Imperial County, California.

As reported in the December 2013 press release, the new technical information obtained from the four deep core holes completed in the recent drill program has proven to be invaluable with respect to understanding the geology of the higher grade gold-silver veins.


As a result of the detailed planning of core holes drilling is scheduled to begin in February.

Teras’ primary objective for 2014 is to increase the grade of the precious metal resource via delineation of high grade precious metal mineralization, thus enhancing the total in ground gold and silver ounces within the existing NI 43-101 resource.


Detailed geology that has recently been garnered from core logging indicates that the higher grade gold/silver veins are dominantly sub-vertical.

The specific geometry of the high grade veins was not well understood in the past because the existing geologic model was interpreted from reverse circulation drill chip logs obtained from a majority of vertical drill holes. The new deep core holes clearly illustrate the sub-vertical nature of the veins as shown in the photos below:

In addition, detailed analyses of the assay results reveal specific linear trends of high grade precious metal mineralization that follow a distinct west-northwest direction.

These linear high grade zones are illustrated on the following map that was received in late December 2013, along with the geophysical resistivity showing hard or silicified rocks in blue and white which are commonly mineralized:

This new information, along with the knowledge of sub-vertical high grade vein control, is of extreme importance in positioning the next round of core holes, which is currently in progress.

These new high priority targets will be tested by angled core holes drilled along fences to define continuity of sub-vertical high grade gold/silver zones.

Mr. Peter Leger, President and CEO of Teras Resources, commented “This new data has significantly advanced our understanding of the higher grade gold-silver veins, which we believe will lead to enhancing the grade and expanding the size of the current NI 43-101 precious metal resources at Cahuilla.”
