De Grey Mining Confirms Spodumene & Extends Strike Length at King Col
West Perth, WA / March 1, 2018 / JMN Wire / De Grey Mining Ltd (ASX: DEG) (“De Grey”, “Company”) is pleased to advise that detailed petrology on drill chips from previously reported RC drilling has significantly advanced the project with the presence of spodumene confirmed in the samples and results from the recent King Col soil sampling program successfully defining substantial extensions to the overall anomalous lithium zones.
Technical Director, Mr. Andy Beckwith, commented:
“The recognition of spodumene rich mineralisation is a significant geological advance, as this is the most sought-after lithium rich mineral mined around the world. The nearby Pilgangoora and Wodgina deposits are both Tier 1 spodumene rich pegmatites.
The large lithium-in-soil anomalies now span over 7.5km of strike length with only a small portion having any drill testing to date, yet this limited drilling has yielded high-grade results in this early exploration phase.”
- Spodumene-quartz mineralisation identified within De Grey’s high-grade drill intercept of 17m @ 2.55% Li2O.
- Spodumene, a lithium bearing mineral, identified in petrology within the overall intercept of 17m @ 2.55% Li2O from 13m in hole KRC012 (previously reported). Spodumene is the main lithium bearing mineral mined from most hard rock lithium mines around the world.
- Spodumene-quartz mineralisation associated with the higher grade (4.84% Li2O) portions of KRC012 intercept. Petalite and Lepidolite, both lithium bearing minerals, also confirmed.
- Pollucite, a Cesium bearing mineral, also identified from the previously reported high grade Cesium intercept of 1m @ 8.63% Cs2O from 25m in hole KRC011.
- Encouraging soil sampling results substantially extend target strike length and define a second large anomaly;
- Main King Col lithium in soil anomaly extended from 2.0km to 4.8km long
- New 3.0km long anomaly defined to south east
- A diamond drill hole planned in Q2 2018 will twin the high-grade lithium mineralisation of KRC012 to determine distribution and percentages of the lithium bearing mineral assemblage.
