Twenty Seven : Significant Soil Results at Rover Gold Project

ASX: TSC

ASX ANNOUNCEMENT

6 December 2021

For personal use only

Significant soil results confirm prospectivity of the

Edale Shear at the Rover Gold Project

KEY POINTS:

• Recent soil samples have identified new follow up targets in areas with very limited histrorical work
• Highly elevated gold-in-soil results received, with samples up to 420ppb Au
• Good correlation between geochemical anomalies and interpreted regional structural features
• 2,000m RC drilling program to commence this month, and will focus on the highly prospective Blue Hills, Four Corners, Harmonic and Creasy 1 Prospects
• Drilling will test below and along strike of the Harmonic and Creasy 1 Prospects, whilst also targeting the recently identified gold-in-soil anomaly where a 1.15g/t Au (1150ppb) sample was returned1

Commenting on the soil results, CEO Simon Phillips said:

"The soil program has fulfilled its objective of providing a low cost, first-pass geochemical assessment of the extensive strike length of the Edale shear. To obtain values up to 420 ppb gold from an area that has seen limited geological sampling is highly encouraging. Several very promising targets justify follow-up with infill soils, to better define and characterise potential drill targets. We are also looking forward to commencing our RC drilling program at Rover this week and will provide updates on progress in due course."

Twenty Seven Co. Limited (ASX: TSC) ("TSC" or "the Company") is pleased to report that recent soil results collected from the Rover Gold Project in WA have returned positive results, including a gold-in-soil result of 420ppb along with numerous samples that are above 10ppb Au.

A soil sampling program comprising 243 samples was conducted in October 2021 at the Rover Gold Project, with the location of the lines based on the magnetic interpretation and the extensions of the previous soil programs.

Initial results from this program both confirm and extend the known gold-in-soil anomalies already identified at Middle Well, Four Corners and Blue Hills. Some isolated and low tenor gold

anomalies are also of interest due to the geological setting along the Edale Shear given that further south towards Harmoinc and Creasy 1 low tenor gold surface anomalisms identified primary mineralisation at depth. It is important to note that some major discoveries have been made in the Kalgoorlie district beneath weak soil anomalies such as Kanowna Belle (4 million Oz Au - 350m >60 ppb Au-in-soil2).

TSC has identified several multi-point anomalies from its broad-spaced,first-pass geochemical survey. In particular, nine samples have returned +10 ppb Au and justify further follow-up work. Full results of the sampling program are set out in the attached Table 1.

A 2,000m RC drilling program is scheduled to commence at Rover this week, with additional soil sampling programs planned to expand on the most recent soil program in the coming months.

Twenty Seven Co. Limited (ASX: TSC) is an ASX-listed explorer. TSC's Australian assets comprise two tenure groupings detailed briefly as follows:

WA Archaean Gold assets:

• Mt Dimer Project: is made up of mining lease M77/515 and exploration license E77/2383. The project is highly prospective for Archean gold.
• Yarbu Project: This project is located on the Marda Greenstone belt ~ 80km to the northwest of the Mt Dimer Project. Yarbu consists of three exploration licenses (E77/2442, E77/2540 and E77/2539) which cover approximately 223sq km and are highly prospective for Archean gold deposits.
• Rover Project: TSC's 100% owned Rover project is located near Sandstone in a base metals and gold mineral rich area associated with Archean greenstone belts. The Rover Project is a large 460sqkm tenure package covering two linear Archean greenstones, with a combined length of around 160km. Historically the area is underexplored and is currently undergoing a resurgence in exploration.

NSW Iron Oxide-Copper-Gold and tin assets:

• Midas Project: is prospective for iron oxide copper gold (IOCG) and is located 40km NE of Broken Hill.
