Strong Copper, Gold, and Tin

Mineralisation Identified at Trident Project

KEY POINTS:

• High grade copper assays returned from Trident Project in NSW with rock chip samples up to 17.60% Cu recorded
• Up to 1.275g/t Au recorded from the same area as highly anomalous copper results
• Multiple tin results greater than 1% received in several samples with up to 2.44% tin also recorded
• Coupled with the high tin results are highly anomalous niobium, tantalum and rubidium grading up to 1080ppm, 676ppm and 3080ppm respectively
• Initial exploration suggests pegmatites appear to be NYF (niobium-yttrium- fluorine) and not LCT (lithium-caesium-tantalum) pegmatites
• Numerous areas of high-grade copper and gold to be followed up on the next sampling program as a matter of priority
• Selective samples will be assayed for Rare Earth Elements ('REE') analysis to ascertain rare earth occurrences
• Positive copper and gold assays confirm the potential for IOCG mineralisation at Trident

Commenting on results from the Trident sampling program, CEO Simon Phillips said:

"We are pleased with these early results from our sampling at Trident which confirm the highly prospective multi element nature of the project. We are very encouraged by the strong copper, gold and tin mineralisation identified. The Trident Project remains significantly underexplored and we believe we are only scratching the surface in terms of the mineralised potential of this region.

We look forward to the TSC geological team following up these results with further work early in the new calendar year."

Twenty Seven Co. Limited (ASX: TSC) ("TSC" or "the Company") advises that it has received assay results from its first pass rock chip sampling program at the Trident Project located in NSW (Figure 1).

A total of 152 rock chip samples have been taken from across the northern portion of the tenement, (see Figure 2) within areas of historically reported highly anomalous copper, gold, tin and other critical elements.

Full results received to date are presented in tables 1 and 2 below.

The rock chip program was undertaken to target copper and gold mineralisation along with confirmation of the historical lithium samples taken by previous explorers 1,2 &3. The program was also designed to assist the Company to build its understanding of the regional geology, mineralisation potential and mineralisation patternation within this copper-gold province and tin province.

From the results received numerous follow up areas have been identified in respect of Cu, Au, Nb, Ta, and Rb.

Analytical results from the rock chip samples have been received by the Company, with significant results from numerous areas that require follow up work. Figure 3 shows the rock sample that returned 17.6% copper and Figure 4 shows the sample location that returned 1.275g/t Au.
