(Adds Cora Gold response, context, details)

JOHANNESBURG, Jan 10 (Reuters) - Hummingbird Resources HUMR.L is "evaluating the immediate risks" to its supply chain from economic sanctions imposed on Mali by the Economic Community of West African States (ECOWAS), the junior gold miner said on Monday.

The 15-state regional bloc said it would also shut borders and sever diplomatic ties in response to Mali's delay in holding elections following a 2020 military coup.

Mali is one of Africa's biggest gold producers with companies like Barrick Gold ABX.TO , B2Gold BTO.TO and Resolute (RSG) operating large mines in the country and many smaller companies exploring for gold there.

A spokesperson for Cora Gold CORAC.L , which has said it plans to start building its Sanankoro gold mine in Mali this year, said the board was monitoring the situation and operations in Mali are continuing as normal.

Barrick Gold, B2Gold, and Resolute did not immediately reply to requests for comment on the possible impact of the sanctions.

Hummingbird owns the Yanfolila gold mine, which was expected to produce under 100,000 ounces last year. Its shares were down 5%.

"Whilst all plans will be made to minimise the potential impact it is too early to say how these sanctions may potentially affect our business," the miner said in a statement, adding that it would provide further updates when appropriate.
