PRESS RELEASE


FOR IMMEDIATE RELEASE: TUESDAY, JUNE 6, 2000
TO: PR NEWSWIRE, NEW YORK, IRW (INC. DOW & REUTERS)


               SAND TECHNOLOGY INC. REPORTS THIRD QUARTER RESULTS

           NUCLEUS QUARTERLY SALES TOP $2M FOR FIRST TIME IN HISTORY.

MONTREAL, CANADA, June 6, 2000 - - - SAND TECHNOLOGY INC. (NASDAQ: SNDT) today
reported a net loss for its fiscal quarter ended April 30, 2000 of $(1,841,867)
or $(0.21) per share on sales of $2,042,918 as compared to earnings of $55,380
or $0.01 per share on sales of $868,855 for the third quarter ended April 30,
1999. Losses from operations were $(1,712,502) for the third quarter of fiscal
2000 as compared to a loss of $(172,941) for the third quarter of fiscal 1999.

Arthur Ritchie, President and Chief Executive Officer, noted that "this quarter
marks a real milestone in the market acceptance of Sand's Nucleus product suite.
Not only did Sand more than double its sales revenues over the same quarter last
year, it is the first time Nucleus product sales have surpassed the $2 Million
mark in a quarter. Sales in the current quarter were almost the same as in the
entire previous fiscal year."

Mr. Ritchie added that "Sand has an order backlog of over $2 million for the
Nucleus product suite going forward and has added ten new customers during the
third quarter. We are continuing to move strongly ahead to broaden our sales
abilities and take advantage of opportunities in deploying Nucleus at our
customers." Mr. Ritchie went on to say that "the company expects to sustain
losses over the next several quarters as it continues to ramp up its sales and
support organization to gain a strong foothold in the marketplace."

Mr. Ritchie emphasized that "Sand has noticed a marked increase in the
acceptance of its Nucleus products in the market place and a much enhanced
receptiveness to its marketing strategies."

data mining, data marts, data warehouses and on-line analytical processing
