WESTMOUNT ENERGY LIMITED

("Westmount" or the "Company")

Re-commencement of drilling operations at Jabillo-1, Canje Block, offshore Guyana

Westmount Energy Limited (UK AIM: WTE.L, USA OTCQB: WMELF) is pleased to note the announcement by the Maritime Administration Department, Guyana, that the Stena Carron drillship will re-commence exploration drilling operations at the Jabillo-1 wellsite on the Canje Block, offshore Guyana on the 5th June 2021.

Jabillo-1 is the second of 3 exploration wells scheduled for drilling on the Canje block in 20211. Previously published information indicates that Jabillo-1 is a circa 1,000 MMbbl oil prospect targeting a Late Cretaceous, Liza-age equivalent, basin floor fan1.

Westmount holds an indirect interest in the Canje Block as a result of its circa 7.7% interest in the issued share capital of JHI Associates Inc. ("JHI")2. Following a 2018 farm-out to Total, JHI is carried for the drilling of the Jabillo-1 well and is funded for the drilling of additional wells.

The Canje Block is currently operated by an ExxonMobil subsidiary, Esso Exploration & Production Guyana Limited (35%), with Total (35%), JHI (17.5%) and Mid-Atlantic Oil & Gas Inc. (12.5%) as partners.

Westmount is also pleased to announce that the Company's updated corporate presentation can be viewed on, or downloaded from, its website at http://www.westmountenergy.com/presentations/.
