It's just a guess but maybe they've been operating under a different name. They formed the company just before the ANN which suggests they did so to facilitate the agreement with BBX.
The blurb in the ANN gives a decent outline:
Technical Co-operation Agreement
BBX has signed a Technical Co-operation Agreement with the unlisted Republic of Ireland-based technology and exploration company, Lómhara Tech Limited (Lómhara).
Lomhara, who holds interests in two exploration properties in the US and research facilities in Colorado, North Carolina and Melbourne have for a number of years been developing technologies for recovering high levels of precious metals from ores which don't respond to conventional analytical techniques. This agreement will provide BBX with direct access to key Lómhara consultants in Australia and the USA.
