This was a blow to the union's attempt to stop the companies from sidestepping it.
[DATA AMS:Anglo American Platinum], [DATA IMP:Impala Platinum] and [DATA LON:Lonmin] took their wage offers directly to strikers after talks with the Association of Mineworkers and Construction Union (Amcu) to end the five-month strike failed.
Amcu objected to the move and filed an urgent application to have it halted, but the union's lawyer, Jayson Kent, said the court had thrown it out, arguing it was not an urgent matter.
"We were concerned that urgency might be an issue and it's turned out that it was the issue that has ultimately resulted in our failure here today," he told reporters outside the court. "There are other avenues that we could consider."
The labour court is currently mediating the dispute and new mining minister Ngaoko Ramatlhodi has assembled a government team to negotiate a solution to what is already South Africa's longest and most costly labour dispute.
"The government gave proposals to all parties on Friday and we now have to consider them for approval," said Impala Platinum spokesman Johan Theron.
The proposals were made by the government team after the producers and union presented their positions, he said, adding that the employers had not revised their pay offer.
AMCU negotiator Brian Ashley told Reuters the union would meet on Monday to consider the proposals.
AMCU is demanding a basic monthly wage for its members of 12,500 rand within three to four years, while the companies have offered pay hikes of up to 10 per cent that reach that figure by 2017 if ancillary benefits are also included.
The strike is having a major impact on the wider economy, pushing into contraction in the first quarter.
It has spilled over into the second quarter, raising fears that Africa's most advanced economy could head into recession this year. However, new Finance Minister Nhlanhla Nene said this would not happen.
