Cresval Capital Corp., a junior precious metals and copper exploration company, has provided an update on its exploration strategies for the fully owned Mike copper porphyry prospect and the fully owned New Raven gold/silver prospect.
Situated in the Lillooet Mining Division in southwest British Columbia, the focus of the New Raven gold/silver prospect and the Mike copper porphyry prospect is to carry out more surface work to additionally delineate targets for drilling operations later this year.
New Raven Gold/Silver Prospect
In late 2018, additional soil sampling work was conducted at the New Raven gold/silver prospect that not only improved the NNW-SSE striking gold zone but also established the presence of a parallel flanking silver zone. Through this sampling work, the gold zone was extended further north towards the newly identified Pallas occurrence. Overall, the New Raven gold/silver prospect presently has gold mineralization indications along 2.7 km of strike. Host rocks are basically altered greenstones called listwanites.
On the whole, the geological setting is analogous to that hosting the Bralone-Pioneer mine that is located 45 miles to the northwest and which yielded 12.6 m tons of ore at a grade of 9.3 g/t gold. Overall, the fieldwork performed by Cresval Capital has identified six strong occurrences of gold over roughly 600 m of strike toward the southern end of the New Raven gold/silver prospect. Assay results from channel and grab samples gathered at these gold occurrences ranged from 0.44 g/t to 106 g/t gold.
At the New Raven trend, scheduled preliminary fieldwork will extend sampling and alteration mapping inside the trend and also select the most potential of prevalent targets for diamond drilling.
Mike Copper Porphyry Prospect
At the Mike copper porphyry prospect, preliminary fieldwork will focus on two regions of robust copper soil anomalies adjoining a post mineral basaltic cap. Additionally, the Russnor soil copper anomaly situated on the east boundary of the basalt lies west of old workings with copper related to an invasive breccia, in which 0.3 % copper over 36.6 m was intersected through drilling. A coincident airborne radiometric anomaly with a potassic alteration signature—a trait of productive parts of porphyry copper systems—additionally improves this region as a major drill target. In a similar way, the extensive copper-gold soil anomaly at the Windy Copper demonstrating on the north side of the basalt cap is to be more thoroughly prospected and soil sampled.
In both regions, comprehensive ground geophysics has been scheduled to help in identifying modified areas that, along with strong soil copper anomaly and radiometric potassic signatures, become main drill targets.
