Pacific Ridge Exploration Ltd. is pleased to announce results from surface exploration programs at its Eureka Dome gold project, White Gold District, and OGI Zinc project in Selwyn Basin.
Soil sampling defined a gold soil anomaly with a strong epithermal gold signature in the headwaters of Eureka Creek. At OGI Zinc, the Company confirmed the presence of a large and strong zinc-silver soil anomaly.
The 2017 soil survey defined a gold soil anomaly with associated anomalous values of arsenic, antimony and mercury. The source of this anomaly is interpreted to be structurally controlled, epithermal-style gold mineralization associated with the Eureka Creek fault zone. Creeks from streams downslope of this anomaly are enriched in gold, with values ranging from 360 ppb to 2,190 ppb gold. The Company plans a program of detailed mapping, prospecting and trenching to determine the source of this anomaly.
The target at OGI Zinc is a stratabound, sedimentary exhalative (SEDEX) base and precious metal deposit within the Selwyn Basin. Historical exploration during the period 2011 to 2015 defined a zinc-silver soil geochemical anomaly approximately 1,000 m in length and 500 m wide. The anomaly is strongly anomalous in zinc (2,000 to +10,000 ppm), silver (<10 ppm to +50 ppm) and enriched in other elements including nickel, arsenic, molybdenum, barium, phosphorous and vanadium. The 2017 program increased the density of sampling through the anomaly and confirmed its size and intensity. While sampling of the underlying sediments encountered some enrichment in metals, the source of the soil anomaly was not discovered. The Company is considering a program of mechanical trenching to seek the bedrock source.
In addition, Pacific Ridge continues to evaluate new projects for acquisition.
