Standard Lithium Drills and Samples Highest Confirmed Grade Lithium Brine in Arkansas - Seite 2

Examples of high porosity Smackover Formation rocks recently recovered from the Montague #1 well (that is part of Standard Lithium’s current drilling program) are also shown in Figure 2.

Figure 1: South West Arkansas (SWA) Project overview map showing the location of the re-entered well (Beulah-Taylor #1) with associated lithium concentrations in brines sampled from the Smackover Formation. Other data on the map are lithium concentrations in brines sampled by the Company in 2018 from existing wells on the southern edge of Standard’s project area.

Brines from the Beulah-Taylor#1 were sampled using a workover rig from several different zones in the Smackover Formation during March and early April, and the lithium concentrations of those samples are reported in Table 1 below. All brine samples were analyzed at multiple analytical laboratories (both third-party and also at the Company’s analytical facility in El Dorado, Arkansas) in order to confirm sample quality and maintain QA/QC procedures. The Standard Lithium data provided in Table 1 below were all analyzed, performed, and reported by Western Environmental Testing Laboratories of Sparks NV, a third-party, accredited testing facility.

Table 1: Beulah-Taylor#1 Lithium Brine Analyses in South West Arkansas Project Area

Smackover Sampling Name [1]	Lithium concentration (mg/L) [2]	Average Lithium concentration (mg/L) [3]
Zone 1 (Upper Smackover)	531 / 569	563
Zone 2 (Upper Smackover)	581 / 574
Zone 3 (Upper Smackover)	570
Zone 4 (Middle Smackover)	551

Notes:
[1] Smackover Formation descriptors (Upper, Middle, and Lower) are a local project area naming convention.
[2] Where two lithium analyses are provided, they represent the main sample and a blind duplicate for QA/QC purposes.
[3] Unweighted mean lithium concentration from the four representative brine samples (plus duplicates) from Beulah-Taylor#1.
