Newfield Resources (NWF) has provided an update on the development of its Tongo Diamond Mine in Sierra Leone.

The company advised exactly 845 metres of underground development has been completed to date.

Importantly, the ASX-lister also said the outbreak of the new COVID-19 variant, Omicron, hasn’t affected operations.

NWF said its primary focus was the development of the Return Air Way (RAW) to the first ventilation shaft.

The RAW is being developed along strike of the Kundu A kimberlite segment with each blast providing ore for stockpiling.

The ore is then being stockpiled at the company’s bulk sample plant for processing, which is located nearby.

Additionally, the materials stock revealed the Kundu decline development has progressed to the first mining level.

This will lead to the first mining stopes being established at Tongo as well as the first run of mine ore.

Newfield Executive Director Karl Smithson said he was pleased with the progress to date at Tongo.

“Some 845 metres of underground development has been achieved to date. Kimberlite ore is being yielded from the RAW on the Kundu kimberlite, and we are currently stockpiling this at our bulk sample plant for processing,” he said.

“The decline towards mining Level-1 on Kundu is also progressing which will lead to the first mining stopes being established at Tongo and providing the first run of mine ore.

“The operations have not been adversely affected by the various worldwide travel restrictions caused by the COVID-19 Omicron variant, but we continue to remain vigilant and maintain our strict screening and sanitation protocol on the mine site.”

Following the post-market-close update, shares in Newfield Resources opened Friday at 35 cents each.
