It said results from the first batch of summer prospecting samples had returned assays from the Grunwald zone of up to 6.1g/t gold, 196g/t silver, 0.111% copper, 1.49% lead and 15.1% zinc, plus two new base metal zones north of the Ataman zone returning up to 17.3% lead, 6.45% zinc and 126g/t silver.

"Work by the Mountain Boy geological team over the past year, along with input from a leading authority in this type of geology (Dr Bruce Gemmell) supports a geological model of an extensive VMS district encompassing the Surprise Creek property as well as MTB's extensive BA property, located south of the highway," Mountain Boy said.

It had struck an option agreement to acquire BA and Surprise Creek from its 50% joint venture partner at the properties, Great Bear Resources, in June 2017.

Mountain Boy recently said the wealth of data from more than a century of piecemeal exploration by various companies was being looked at comprehensively for the first time.

The company increased its holdings in the Golden Triangle last month, acquiring 4,140ha in an all-scrip transaction and a further 828ha through staking, comprising the More Creek property about 40km northwest of the historical Eskay Creek mine and adjacent to Newmont Lake.

It had sold its stake in the Silver Coin property in the Golden Triangle to Ascot Resources last year.
 
Mountain Boy had $1.5 million (US$1.1 million) in working capital at May 31.

Its shares have ranged between C15-32.5c over the past year and closed down half-a-cent yesterday to 23c, to capitalise it at $8 million (US$6 million).
