Burley\u2019s Chubb project in Quebec has delivered a strong set of assay results confirming prior visual estimates of pollucite mineralisation.
\nHigh-grade lithium was expected, but \u2018high-grade caesium-bearing mineral pollucite has also piqued company interest.
\nSignificant pollucite mineralisation in LCT pegmatites are said to be a rarity<\/p>\n

\u00a0<\/p>\n

Special Report<\/em><\/strong>: Burley Minerals, primarily on the hunt for lithium in Canadian hotspots Quebec and Manitoba, has not only confirmed high-grade spodumene at its Chubb project, but a high-value pollucite find to boot.<\/strong><\/p>\n

\ufeff<\/span><\/div>\n\n

If Burley Minerals (ASX: BUR)<\/strong><\/a> was very pleasantly surprised (and it was) to make a recent chance find of pollucite at its highly prospective Chubb lithium project in Quebec, it has strong reason this week to allocate more of the company\u2019s resources and attention.<\/p>\n

A double whammy of assay results from Chubb, for both lithium and caesium,\u00a0has\u00a0just come back from the lab, and the figures (see further below) have excited the company.<\/p>\n

If you\u2019re wondering what on\/in earth pollucite is, then fair enough.<\/p>\n

It\u2019s the premium caesium-bearing mineral, classified as critical by the USA and Canada.<\/p>\n

Caesium\u2019s primary use is as a specialty additive to fluid used in high-pressure, high-temperature, oil-well drilling and, pollucite is regarded as something of a rarity in economic deposits.<\/p>\n

As Burley MD and CEO Stewart McCallion told Stockhead<\/em> recently<\/a>, \u201cthere are no mines currently producing pollucite\u201d with recent reports suggesting that pure caesium was being sold at nearly US$98\/gram.<\/p>\n

\u201cThat\u2019s 50% more than the current gold price,\u201d McCallion noted.<\/p>\n

The Chubb project, by the way, is close to Canada\u2019s only operating lithium mine, the 58Mt @ 1.23% Li2O North America Lithium (NAL) operation jointly run by Sayona Mining (ASX:SYA)<\/a> and Piedmont Lithium (ASX:PLL)<\/a>.<\/p>\n

Double take \u2013 BUR\u2019s latest assay results <\/strong><\/h2>\n

The company\u2019s latest assay data has confirmed what it describes as high-value, highly evolved, LCT pegmatite with pollucite and high-grade spodumene intersections within the southern extent of the spodumene bearing Main Dyke at Chubb.<\/p>\n

The strike is at least 60m of strong \u00a0pollucite mineralisation, which is still open down plunge.<\/p>\n

The now-confirmed pollucite results were intersected in holes CLP-038 and CLP-063 with the former previously reporting: 2.8m at 6.8% Cs2O (caesium oxide) in high-grade pollucite and 5.3m at 2.3% Li2O including 2.3m at 3.9% Li2O in spodumene.<\/p>\n

Meanwhile, assay results from hole CLP-063 confirm earlier visual estimates of 11m at 1.7% Li2O in high-grade spodumene, and 4m at 2.4% Cs2O including 2m at 4.2% in high grade pollucite intersected within the spodumene zone.<\/p>\n

\u00a0<\/p>\n

\u2018Very highly evolved\u2019<\/strong><\/h2>\n

According to the company, the presence of both spodumene and pollucite in the same zone reflects a very evolved LCT pegmatite.<\/p>\n

\u201cBurley Minerals are thrilled to discover this premium pollucite zone in the Main Dyke at Chubb Central, where we have already defined significant and continuous spodumene mineralisation,\u201d McCallion said of the additional new pollucite finds.<\/p>\n

\u201cThe pollucite mineralisation confirms a very highly evolved, high value, LCT pegmatite system at Chubb Central Mineralised Zone.<\/p>\n

\u201cSignificant discoveries of pollucite in LCT pegmatites are very rare and only three pollucite mines have operated in recent times \u2013 Tanco Mine (Manitoba), Sinclair Mine (Western Australia) and Bikita Mine (Zimbabwe).<\/p>\n

\u201cPollucite has only been found in significant amounts in large, highly differentiated and evolved Lithium Caesium Tantalum pegmatite systems which bodes well for the prospectivity of the Chubb Project for further discoveries of LCT-related minerals.\u201d<\/p>\n
