Cream Minerals Reports Very Positive Metallurgical Test Results For Nuevo Milenio

 
94% GOLD RECOVERY AND 90% SILVER RECOVERY EMPLOYING SCOPING FLOTATION AND CYANIDATION OF TAILINGS

Vancouver, BC - November 17, 2009 - Cream Minerals Ltd. (TSX-V - CMA) ("Cream" or the "Company") is pleased to announce the completion of four preliminary Metallurgical Tests. The tests were conducted by Inspectorate America Corporation on samples derived from Nuevo Milenio. The best results were obtained by a combination of Flotation with one cleaning circuit followed by cyanidation of the flotation tailings producing a recovery of 94% for gold and 90% for silver. These are very encouraging test results and indicate the probability of very high gold and silver recovery rates for Nuevo Milenio.

The purpose of the tests was to obtain initial results on gold and silver recovery on samples obtained from Nuevo Milenio and to establish parameters for further detailed metallurgical tests. The samples were taken from fresh and partially oxidized mineralized zones at Nuevo Milenio. Test materials were collected from historical Spanish workings on Dos Hornos 1 (cross-cut adit 4, Shaft 5 Sublevel 3), Veta Tomas ((Shaft 12) and Once Bocas (Stope). The samples were shipped to Inspectorate America Corp., Exploration & Mining Services, PRA Metallurgical Division of Richmond, B.C., Canada, which conducted the metallurgical tests.

The initial Metallurgical Tests consisted of Cyanide Bottle roll tests, a Scoping Flotation test with one Cleaner circuit, followed a Cyanide Leach of the flotation tailings and a Thiosulfate Leach Test.

The following represent the average recovery for each test completed:

1) Cyanide Bottle Roll Test - 24 hours:Gold 89%Silver 62%
    Cyanide Bottle Roll Test - 72 hours:Gold 94%Silver 78%
2) Scoping Flotation Test, one cleaning circuit:Gold 66%Silver 81%
3) Cyanide Bottle Roll Test of Flotation Tails:Gold 88%Silver 56%
4) Scoping Flotation and Cyanidation of Tailings:Gold 94%Silver 90%
5) Thiosulfate Leach:Gold 21%Silver 76%

The tests results show that mineralization from Nuevo Milenio is amenable to both, Cyanide leach and or Flotation recovery techniques, followed by the Cyanide leach of flotation tailings.

Additional tests are required to determine the effect of a Gravity circuit on total gold recovery and to reduce retention time in the Cyanide leach circuit and / or enhance gold recovery in the flotation tests. Further tests would include a second or third cleaning circuit in the flotation test to increase silver recovery and a gravity circuit to scalp off coarse gold. These adjustments may be sufficient to upgrade gold and silver recovery to an acceptable level without the Cyanidation of flotation tailings. The Leach results are based on a 72 hour leach cycle from composite underground channel samples. The average particle size was 80% at 72 micrometers (passing 200 mesh screen). The average consumption of Cyanide (NaCN) was 0.92 kg/ton and average consumption of Lime was 1.68 kg/t. To view the sample data and details of the test results please click on www.creamminerals.com

Cream Minerals Ltd. and Roca Mines Inc. entered into an option agreement on July 24, 2009 under which Roca Mines agrees to spend $US12 million on the Nuevo Milenio Project by July 24, 2013 to earn a 50% interest. Roca Mines Inc. has a second option to earn a further 20% interest by funding a NI 43-101 Compliant feasibility study for a total interest of 70% in the Nuevo Milenio property. The NI 43-101 Compliant feasibility study must be completed within three years of the date Roca Mines Inc. provides notice to Cream of its intention to proceed with the second option.
