Ridgestone Mining drills 1.5m of 36.1 g/t Au at Rebeico

2019-01-17 08:43 ET - News Release

Mr. Erwin Wong reports


Ridgestone Mining Inc. has received final assay results from an initial drill program conducted on its Rebeico gold-copper project located within the prolific Sierra Madre gold belt of Sonora, Mexico.

Drilling was designed to test for gold and copper mineralization down-dip below historical workings along a portion of the greater-than-one-kilometre-long Alaska vein.

Assay results for the first four drill holes (18REB1 through 18REB4) were reported in the company's Dec. 13 news release.

Highlights of the assay results from holes 18REB5 through 18REB12 are summarized in the table.

Hole ID       From (m)     To (m)    Interval (m)    Au (g/t)     Cu (%)

18REB5          82.00      83.00            1.00        5.61       0.30

18REB10        103.64     105.14            1.50       36.10       1.22

A complete summary of results from the drill program along with maps and sections is available on the company's website.

Significantly, hole 18REB8 intersected highly anomalous bismuth values (2,800 parts per million Bi) with the 9.59-gram-per-tonne-gold assay from 103.64 metres to 105.14 m. As previously reported, anomalous bismuth may be indicative of a high-temperature, intrusive-related style of mineralization potentially proximal to a copper-gold porphyry or IOCG (iron oxide copper gold) system.

The high gold and copper values encountered along the previously undrilled Alaska vein in this first phase of drilling are extremely encouraging and further drill campaigns are warranted. It should be noted this first drill program investigated only very shallow depths and only a lateral distance of 500 m along the greater than one km Alaska vein.

Jonathan George, of partner YQ Gold de Mexico SA de CV, commented, "These results, together with those of previous geochemical and geophysical programs undertaken by Ridgestone and YQ Gold, provide compelling evidence of the potential for a significant new discovery in a relatively unexplored region of the Sonoran Sierra Madre mineralized belt."

The Rebeico drilling program was managed by Ridgestone's partner, YQ Gold de Mexico SA de CV. Drill core was transported by YQ Gold personnel from the drill sites to a secure logging and sample storage area on a daily basis. After logging by YQ Gold geologists, intervals selected for sampling were sawed in half lengthwise. The one-half core samples were placed in prenumbered sample bags and weighed. Blank samples were inserted into the sample stream for quality assurance/quality control purposes. YQ Gold personnel transported the samples to the ALS Minerals preparation laboratory in Hermosillo, Sonora. After preparation, sample pulps were air freighted by ALS to its assay laboratory in North Vancouver, B.C. Gold was determined by fire assay fusion with an atomic absorption finish. Silver and 31 major, minor and trace elements were determined by ICP-AES following four-acid digestion.
