The miners, who were covered in mud, were whisked away by officials before speaking to reporters. Rescuers briefly stopped operations due to rain.
Local Government Minister July Moyo said in a statement on Friday the government had declared the incident a disaster and that up to 70 people could have been trapped in the pits.
Battlefields and surrounding areas are rich in gold deposits and popular with artisanal miners, known locally as "Makorokoza" or hustlers, who use picks and shovels and generator-powered water pumps. The makeshift shafts and tunnels can easily collapse in the rainy season when the ground is soft.
The pits are dotted around a clearing some 8 km from the main dirt road. On the edges are shacks made of plastic which serve as accommodation for those digging for gold.
Anxious relatives and other miners have continued to camp at the mining site hoping to see their colleagues amid frustration that the rescue process was taking too long.
