The drill program will consist of around 5,600 metres targeting areas on the Core and Central properties as well as previously untested occurrences of spodumene-bearing pegmatite on regional properties.
Piedmont president and CEO Keith Phillips said: “We are excited to once again have drill rigs in the field.
“The Carolina Tin-Spodumene Belt is one of the world’s most significant spodumene occurrences and there are many high-priority targets remaining on our properties.”
“Growing mineral resources”
Phillips said the overall aim of the drilling program was to focus on opportunities to grow the mineral resources.
He said: “Spodumene is the dominant feedstock for the fast-growing lithium hydroxide market and with over 80% of the world’s hydroxide currently being produced in China, this is an opportune time for Piedmont to grow its mineral resources in the United States.”
Around 50% of the total drill holes are allocated for the eastern portion of the Core Property.
The holes will test two exploration target areas previously identified, plus Area 5 which is outcropping mineralisation with assays up to 2.10% lithium.
Several areas of low mineralisation potential will also be tested to determine if they offer additional resource potential or are better suited for waste rock storage and/or mine infrastructure.
At the Central property, five drill holes will test the previous exploration target and build on the phase four drilling results reported in January.
Two holes are designed to test to the south and downdip of the intercepts reported in hole 19-CT-019 of 36 metres at 1.11% lithium and 44.9 metres at 1.3% lithium.

The remaining drilling will be distributed on Piedmont’s regional properties.
Drilling at Area 1 will target a large soil anomaly, along with outcrops of spodumene-bearing pegmatite that range up to 2.37% lithium.
Initially, Area 2 and 3 will receive limited drilling that will target soil anomalies and spodumene in outcrop.
At Sunnyside, soil anomalies and newly identified spodumene pegmatite occurrences will be the focus, as well as potential follow-up drilling from the 2018 results of 20.1 metres at 1.42% lithium.
