Highest Grade Identified so far from Bradda Head's Exploration Programme

Bradda Head Lithium Ltd (AIM: BHL), the North America-focused lithium development group, is pleased to announce assay results with intercepts of over 2,000 ppm Li identified in its third twinned hole at its 100% owned Burro Creek East Project ("Burro Creek"), which emphasises the opportunity for resource growth at this target site.

Highlights:

· Hole BCE21-03 discovered previously unknown, but anticipated, lithium mineralisation within the Lower Clay zone at Burro Creek East and highlights again that there is significant potential for an increase in the Lithium Mineral Resource as a consequence. The Lower Clay zone was not tested previously at this location. (See map for drill locations https://www.braddaheadltd.com/media/image-library/2021-burro-creek-east-drilling-programme/).

· Assay results from the third twinned hole (BCE21-03) confirm the same depth profile in the Upper Zone as previously reported from the 2018 programme.

· The highest grade recorded in the Upper Clay zone at 2,150 ppm Li over 0.6m from BCE21-03, compares with 1,590ppm Li over 1.5m as reported in 2018.

· The highest grade recorded in the Lower Clay zone was 1,910 ppm Li over 1.1m.

· These grades as well as the grades / intersection reported earlier (See RNS dated 25 August 2021) for holes BCE 21-01, and 02 compare favourably with the current JORC compliant estimate of 185kt of Lithium Carbonate Equivalent (LCE) in 2018.

· This current exploration programme at Burro Creek is expected to be completed by mid to late October. All assays should be received within four weeks of the last hole being completed.

Charles FitzRoy, CEO of Bradda Head, commented:

"These positive drilling results are some of the highest grades identified to date at Burro Creek East.  They not only provide further confidence to our geological model, but we believe, also add value and the potential to add further resources to our previously reported numbers of 185kt of LCE.

 The presence of these grades in both the Upper and the Lower Clay Zones reinforces our geological interpretation for the Burro Creek lithium deposit and bodes well for the remaining drilling programme and for the potential at the rest of our Burro Creek claims. The Lower Clay zone was never previously drilled

"It's also worth noting that our geophysical programme commencing at Wikieup, Burro Creek and San Domingo will help us to plan future drill programmes.

It is exciting times, not only in terms of the overall Lithium market space but also as our exploration drill programmes, and on-site field work at all three of our Lithium targets kicks into gear."

Assay results from our third twinned core drill hole at Burro Creek East (BCE21-03) are the highest-grade intercepts drilled to date (highest grade recorded in Upper Clay zone 2,150 ppm over 0.6m from hole BCE21-03, and in Lower Clay zone 1,910ppm Li over 1.1m), and recoveries have remained high, at 94% for this hole.

Bradda is conducting a 10 hole programme at Burro Creek East, consisting of new holes and twinned holes designed to test the 2018 RC drill programme that suffered poor recoveries and was used to estimate the Burro Creek East Inferred Resource in 2018. To date, Bradda has received positive results from this programme, with a 14% increase (RNS 25 August 2021) in grade seen in the Upper Clay zone at the second twinned hole over the same depth profile as the 2018 Reverse Circulation ("RC") hole. It is anticipated that the results and resource revision will potentially lead to both an increase in resource size, grade and increase in confidence classification.

The results at BCE21-03 indicate that the Lower Clay zone here is mineralised with lithium bearing clay. We are excited to start our geophysics programme at our sedimentary assets which will help demonstrate that the thickness of our Upper Clay zone potentially increases to the North and West towards our other claims, which Bradda is in the process of permitting for drill programmes in early 2022.  It might also help to determine the depth to basement below the Lower Clay zone, and where the thickest clay sediments are likely to be.

Bradda is conducting a geophysical programme to enable it to identify where to plan future drill programmes at the remainder of its 47km² of sedimentary assets in Arizona. This will ensure drill holes are placed strategically to ensure no funds are wasted on unnecessary drilling, and that Bradda will maintain as small a footprint as possible whilst drilling.

All remaining holes in the current programme are now scheduled to be completed by mid to late October due to delays from extreme weather, with all assays expected to be received within four weeks of the completion of logging and sampling of the last drill hole.

Technical Glossary

"Inferred Mineral Resource"   the part of a mineral deposit for which quantity and grade (or quality) are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological grade (or quality) continuity. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. An Inferred Mineral Resource has a lower level of confidence that applying to an Indicated Mineral Resources and must not be converted to an Ore Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration

"kt"   kilo tonnes being equal to 1,000 tonnes

"Mt"   Mega tonne, being equal to 1,000,000 tonnes

"ppm"     parts per million, commonly used to express grade in mineral and brine deposits (equivalent to one gram per tonne)

Notes to Editors

Bradda Head Lithium Ltd is a North America-focused lithium development group. The Company currently has interests in a variety of projects, the most advanced of which are in Central and Western Arizona: the Burro Creek project (Burro Creek East Project, and the Burro Creek West Project) and the Wikieup Project.

The Burro Creek East Project has an estimated an Inferred Mineral Resource (JORC) of 42.6 Mt of lithium bearing clays at an average grade of 818 ppm of lithium for 185,000 tonnes of lithium carbonate equivalent (LCE). The Burro Creek East Project also has additional exploration potential for extensions to the current model of between 50,000 to 300,000 tonnes of lithium carbonate equivalent.

The Group intends to continue to develop its three phase one projects in Arizona, whilst endeavouring to unlock value at its other prospective pegmatite and brine assets in Arizona, Nevada and Pennsylvania.

All Bradda Head's licences are held on a 100% equity basis and are in close proximity to the required infrastructure.

Bradda Head is listed on the AIM market of the London Stock Exchange with the ticker of BHL.
