Segerstrom was earlier the geology manager at Freeport-McMoRan's Grasberg project in Indonesia and later COO of Paramount Gold and Silver.

He is also on the board of Almadex Minerals.

Following a week-long detailed field, core and data review, Bam Bam said Segerstrom was "very encouraged by the strong porphyry signature" shown by its flagship Majuba Hill project in Nevada.

"His review of the core from our 2020 drilling provided immediate insight and confirmation for our staged exploration program at Majuba," president and CEO David Greenway said.

"I expect that Larry's experience will bring an important element to understanding the extensive data we have compiled at Majuba."

Bam Bam said Segerstrom's project and core review highlighted "significant enrichment" beneath historical workings at Majuba Hill.

The junior was planning to complete an NI 43-101 technical report in the second quarter, pending receipt of assay results from its 2,654m 2020 drilling programme.

Results already received included 44.5m at 1.41% copper and 97.6g/t silver from surface; and 94.5m at 0.29% copper and 10.2g/t silver from 135.6m.

Bam Bam entered an exploration lease and option to purchase agreement on Majuba Hill in 2018.

It expanded the project by almost 75% in January.

The company said it was focused on acquiring latter-stage copper and copper-silver-gold assets, in response to the forecast growing demand for electric vehicles and renewable power.

It recently announced a three-for-one stock split, expected to take effect next week, to enhance trading volume and assist in acquiring new shareholders for the three exchanges it was listed on.

Bam Bam last raised C$2.59 million in an over-subscribed placement at 50c per unit in November.

Its Canada-listed shares (CSE: BBR) have ranged from 25c-$1.60 over the past year and closed up 1.9% on Friday to $1.06, valuing it at $26.9 million (US$21.2 million).
