Margaret Lake Diamonds announces Arctic Star’s Second Round of Caustic Fusion
Diamond Results Strengthens Previous Results, Sequoia Kimberlite Complex
VANCOUVER, B .C. / September 15th 2021 / Margaret Lake Diamonds Inc. ("MLD" or the
"Company") (TSXV: DIA) (FKT:M85) (OTC PINK:DDIAF) is pleased to announce that
Arctic Star has received the second round of caustic fusion diamond results from the Sequoia
Kimberlite complex. The results are from the remaining half of the drill core recovered from drill
holes DG 2021 04 and DG 2021 05 drilled 202m apart in the central and northern parts of the
Sequoia Kimberlite complex. The results are given in Table 1. The entire core has now been
fused, totalling 505 kg. Usually, half the core is kept for reference, but due to the encouraging
results from the diamond assays in the first half of the core and the encouraging indicator mineral
results reported in the news release dated 7th September, the decision was made to fuse the entire
core.
The samples were taken at the same intervals as the first and they confirm that the different rock
types have different diamond counts. The indicator minerals also demonstrate that the two main
rock types, the volcanoclastic kimberlite and coherent kimberlite are different. While both have
indicators equivalent to those found in the population of large diamonds found around the world,
and diamond inclusion chromite, only the coherent kimberlite has significant “G10” and
eclogitic garnets with diamond inclusion chemistry.
Table 1. Caustic Fusion Results, Sequoia Kimberlite, Arctic Star JV. The Sequoia caustic fusion
results were processed through SRC laboratories of Saskatoon, NQ core was hand split and
bagged in approximately 8kg samples to fit geological intervals where possible, the first half of
core was sent and processed, then the second half of the core was sent using the same sample
intervals. Both samples were sent by chain of custody, SRC is an independent lab and an ISO.
Samples are placed in a kiln, heated to 5080C with caustic soda for 24 hours. The residue is hot
poured through a 0.075mm sieve. The residue is then further chemically treated if required until
just the refractory minerals remain including diamonds. The residue is sized by sieving and then
a mineralogist selects the diamonds. Larger diamonds (>0.5mm) are described and weighed.
