Kaieteur Block - Ratio Petroleum update with respect to the 2(nd) well prospect nomination date

Westmount Energy Limited (UK AIM: WTE. L , USA OTCQB: WMELF ), notes the announcement by Ratio Petroleum Energy Limited Partnership ("Ratio Petroleum") earlier today, that the date for elective nomination, by the operator, of the prospect target for the 2(nd) well on the Kaieteur Block has been extended to the 2(nd) October, 2023. The Kaieteur Block partners agreed to this extension to facilitate continuing geological and geophysical analysis by the operator and integration of recent and ongoing deep play drilling program results on adjacent blocks into the Kaieteur prospect nomination decision. All costs will be carried by the operator during this extension period(1) .

The first well drilled on the Kaieteur block, Tanager-1, evaluated a number of plays - encountering 16 metres of net oil pay (20(o) API oil) in high-quality sandstone reservoirs of Maastrichtian age and confirming the extension of the Cretaceous petroleum system and the Liza play fairway outboard from the prolific discoveries on the neighbouring ExxonMobil operated Stabroek Block. The well was reported as an oil discovery which is currently considered to be non-commercial as a standalone development. Tanager-1 also encountered high quality reservoirs in deeper Santonian and Turonian plays though interpretation of the reservoir fluids in these intervals was reported to be equivocal and require further analysis.

A post-well Netherland, Sewell & Associates Inc. ("NSAI") published CPR(2) indicates that the Tanager-1 Maastrichtian discovery contains a 'Best Estimate' Unrisked Gross (2C) Contingent Oil Resource of 65.3 MMBBLs (Low to High Estimates 17.7 MMBBLs to 131 MMBBLs) - with a 'Best Estimate' Unrisked Net (2C) Contingent Oil Resource attributable to the Kaieteur Block of 42.7 MMBBLs (Low to High Estimates 11.3 MMBBLs to 86 MMBBLs).

Subsequent to the Tanager-1 discovery Hess Corporation increased its working interest ("WI") in the Kaieteur Block from 15% to 20% by acquiring a 5% WI from Cataleya Energy Limited ("CEL").

The current Kaieteur Block partners are as follows:

 Esso Exploration and Production Guyana    35% (operator) 
 Ratio Guyana Limited                      25% 
 Cataleya Energy Limited                   20% 
 Hess Guyana (Block B) Exploration 
  Limited                                  20% 

Westmount holds approximately 5.3% of the issued share capital of Cataleya Energy Corporation(3) the parent company of CEL and circa 0.04% of the issued share capital of Ratio Petroleum the ultimate holding entity with respect to Ratio Guyana Limited.

(1) Announcements by Ratio Petroleum indicate that, under a farm-in agreement executed with ExxonMobil (operator) in 2016, any drilling consequent to the 2(nd) well prospect nomination decision will commence within nine months of the nomination date. The operator, as farminee, continues to bear all farmor JV expenses during the prospect nomination extension period.
