Omega Bars have been thought to have been made by M & B Mining out of Las Vegas Nevada. The original information for this I believe is the trademark filed for the symbol on the bars:
This trademark information is located here: https://trademark.trademarkia.com/mb-72337553.html
Another reference to M & B Mining is this SEC complaint document from 10/8/1969:

as well as this SEC complaint:

What is interesting is Robert Grabar and his wife Lela Osborn Grabar were involved in various other silver companies and I have found no references to the M&B Mining company besides the above few. I believe the corporation was never established after the SEC injuction.
This court case where one company was sued lists some early history of the Grabars:
“In 1968 Robert Grabar and his wife, Lela Osborn Grabar (hereafter Lela Osborn), formed the International Silver Mint Corporation, a Nevada corporation, which was involved in buying and selling raw silver, silver bars and silver coins. The Grabars were divorced in 1973 and the Utah decree purported to effect a liquidation of International Silver Mint Corporation and a division of its assets. Shortly after the divorce, Mr. Grabar formed the IMC Mint Corporation, which is a defendant in this action.”
International Silver Mint Corporation ran numerous newspaper advertisements in 1972 through 1973 with a lot of hype and legal problems from various states in the west. A lot of details are: here.
A rare example of an International Silver Mint Corporation bar looking very similar to an Omega bar…
Even before the divorce, multiple companies appear to have been involved selling Omega silver bars and Universaro rounds (showing the same symbol). “IMC Mint Corporation”, “International Mint Corporation” and “Intermint” all can be found selling Omega hallmarked bars or rounds.
This ad ran numerous times in July 1972 mainly in Utah newspapers…
